Re: Perl install problems OSX 10.4.11
Hi Doug, Just before I create the file I would like to check a few points. but you should edit that so that the first directory, before the first separating colon, is the one that perl 5.10 is in I am not quite sure which is the main Perl folder. /usr/local/bin contains two Unix executable Perl files — Perl and Perl 5.10.1. I assume that this should be the first directory. Which files is PERL5LIB. All the installed modules are stored in /usr/ local/lib/perl5/5.10.1/. Is this the location of the PERL5LIB. If so, do I need the full path /usr/local/lib/ perl5/5.10.1/ or can I use /usr/local/lib/. If the above is correct, then the following is what I think I should write to a plist file. ?xml version=1.0 encoding=UTF-8? !DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http:// www.apple.com/DTDs/PropertyList-1.0.dtd plist version=1.0 dict keyPATH/key string/usr/local/bin:/usr/local/lib:/opt/local/bin:/opt/ local/sbin/string keyPERL5LIB/key string/usr/local/lib/perl5/string /dict /plist opt/local/bin and /opt/local/sbin is taken from a .profile created by MacPorts which I hope will preserve the links for MacPorts.

Would what you have suggested allow get_iplayer find the path to Perl 5.10.1 when I try to run get_iplayer from the terminal? If it does then I don't fully understand your instructions. I assume mkdir $HOME/.MacOSX creates a directory. I tried it but could not find the directory. When I used cat $HOME/.MacOSX/ environment.plist in the Terminal, it seemed to hang. When you say paste the text of the new file here what text do you mean? cat, used that way is waiting for you to paste the text onto the Terminal screen. The text will become the contents of the environment.plist file. The problem is that Apple takes pleasure in making things difficult for users who might be able to muck something up. Those leading dots typically identify files that are private to the system. You can see dotted files with the unix command ls -a for list all. cat stands for concatenate which reads standard input, the terminal screen, and writes to standard out which the directs to a file. You use control-D to terminate the input. I also used cat to display my environment.plist file. You can see the command that immediately precedes the text. But remember that you do have to edit the copy of my file to meet your needs. It is likely that you need only the PATH part but you should edit that so that the first directory, before the first separating colon, is the one that perl 5.10 is in. You probably don't want my personal bin directory but you might want to have a PERL5LIB directory which could also contain modules that would be found wherever perl came from. The /bin and /usr/bin items are pretty much required. cat, for instance, gets found that way. The file format is xml. Entries are in pairs of lines key defines the name and string declares the corresponding value. You might well have a text editor, bbedit or text wrangler (its free cousin) come to mind, that would have no problems dealing with directories whose names start with a dot. That would be fine in place of unix tool cat. You could also use Apple's plist editor but I suspect it would confuse you more than it would help.

I assume that this should be the first directory. Ouch. There really ought NOT to be two perl executables. And they would have to have different names to be allowed in the file system. Is there a Macintosh alias or a UNIX link called perl which points to one of them? You might even find a link/alias in /usr/bin or /bin that some helpful porter put there. The UNIX tool: which perl can be helpful. You can also, in Terminal, do something like cd /usr/ local/lib/perl5/5.10.1 ./perl -v to see just what you have. The ./ tells the kernel to forget about $PATH and look in the current directory only. In real UNIX file systems perl and Perl would be different. Apple's HFS file system treats them the same (well you can change that) but the likes of CPAN and perl itself might not. Which files is PERL5LIB.

Environment variable PERL5LIB adds a directory of your choice to perl's @INC list. The way I use it is to place modules, some of my own creation and others downloaded from the likes of CPAN, into my own directory in my own space where I can control it all. Placing a directory within a perl distribution into PERL5LIB probably won't help much but it's conceivable that you could pick up a module from one distribution for use in another. Personally I have had serious problems with CPAN which are related to my need to keep modules on a disk that is not the startup disk.

The next thing is simply to put full_path_to_'get_iplayer' as the command line in Terminal (on line of course) and it should then list all available BBC TV files in alphabetical order.

To this execute the following in Terminal: /Developer/Tools/SetFile -a v 'full-path-name' and then: killall Finder For 'full path name put successively, /bin, /Library, /sbin, /System and /usr.

So go to '/usr/bin' (now visible) and look for 'perl' -- it will surely be there. The script 'uses' the following: use Env q...@path]; use Fcntl; use File::Copy; use File::Path; use File::stat; use Getopt::Long; use HTML::Entities; use HTTP::Cookies; use HTTP::Headers; use IO::Seekable; use IO::Socket; use LWP::ConnCache; use LWP::UserAgent; use POSIX qw(mkfifo); use Time::Local; use URI; use POSIX qw(:termios_h); So, go to /System/Library/Perl/5.8.8 and look down the list to see that all these things are present.

Re: Perl install problems OSX 10.4.11
OS X 10.4 shipped with 5.8.6, which is what he has. I think some of the misunderstanding is from Terrence's inexperience with perl. Terrence, the modules you're missing aren't missing because you don't have a full version of perl. They're probably missing because they weren't included in the base distribution of perl for version 5.8.6. One of perl's great strengths as a programming language is that there is a library of modules called the Comprehensive Perl Archive Network (CPAN, for short) that allows programmers to build on the efforts of others without having to re-invent the wheel. The modules you're missing are modules to do things like build HTML documents and communicate via web protocols. Anyway, from time to time, modules are added to the base install, so there are modules that come standard with 5.8.8 and 5.10.1 that weren't standard with 15.8.6. It may also be that Apple decides to add modules to the perl it's delivering with OS X. Anyway, none of this is really a problem, since you can install the modules you need, and things should just work. Here's some commands that will help you: $ head -1 get_iplayer This will tell you which perl of yours the iplayer is using. The one I'm using says /usr/bin/perl, but you may have modified yours. $ which perl This shows you which perl you're using by default. If it shows the same perl as the one iplayer is using, you don't need to type the full path when referring to perl when you want to add modules. $ sudo /usr/bin/perl -MCPAN -e shell This will run the CPAN shell, which will allow you to install modules in the library used by /usr/bin/perl. If you're using a different perl than that one, use that path. cpan install LWP cpan install Fcntl cpan install HTML cpan install HTTP These commands tell the CPAN shell to install those modules. Again, I don't think you're going to solve your problem under OS X 10.4 Tiger without installing the modules you're missing, because I don't think your problem is that you don't have a full version of perl. I think the problem is that Apple decided to add optional modules to 10.5 that they hadn't added to 10.4 and aren't part of the base perl install. You can easily add these modules through the CPAN shell, however, so your solution should probably be that. Or upgrade to OS X 10.5. I did that this past weekend to my G4 Powerbook. Yes, I know I'm a full rev behind, but better late than never. -packy On Sep 14, 2009, at 8:04 AM, Mine wrote: Hi, Thank you for the very informative response Alan.

Re: Perl install problems OSX 10.4.11
No, Ultimately unless you know for sure the module is installed by testing to see if it exists I would assume it needs to be installed. Apple's developer tools will need to be installed (or mac ports) if you want to compile and build tools, or in this case perl modules. This is just standard operating procedure if you want to develop in general on the Mac. See Packy Anderson's post on how to install with CPAN, I would advise new people who have not installed/compiled perl on Mac OS X using either the default system perl or their own version to look at the article below, it will help avoid some common pitfalls: http://developer.apple.com/mac/library/releasenotes/OpenSource/PerlExtensionsRelNotes/index.html 2cents - Brian PS: sorry didn't cc the list here it is again.

Re: Perl install problems OSX 10.4.11
Hi, Thanks to all who have responded. I have tried Packy Anderson suggestion but I found that some modules stated that they only come as part of Perl 5.10.1. If I try to install them, it seem that they want to be installed in a location other than that which I have specified. I have Perl 5.10.1 installed but I don't know how set my environment so get_iplayer to use it. MacPorts has set my environment to export PATH=/opt/local/bin:/opt/ local/sbin:$PATH so the version of Perl (5.8.8) installed by MacPorts is being used by get_iplayer.

Re: Perl install problems OSX 10.4.11
Hi Doug, Thanks for the info, but I think this possibly way out side my level of experience. Would what you have suggested allow get_iplayer find the path to Perl 5.10.1 when I try to run get_iplayer from the terminal? If it does then I don't fully understand your instructions. I assume mkdir $HOME/.MacOSX creates a directory. I tried it but could not find the directory. When I used cat $HOME/.MacOSX/environment.plist in the Terminal, it seemed to hang. When you say paste the text of the new file here what text do you mean?

When you say paste the text of the new file here what text do you mean? cat, used that way is waiting for you to paste the text onto the Terminal screen. The text will become the contents of the environment.plist file. The problem is that Apple takes pleasure in making things difficult for users who might be able to muck something up. Those leading dots typically identify files that are private to the system. You can see dotted files with the unix command ls -a for list all. cat stands for concatenate which reads standard input, the terminal screen, and writes to standard out which the directs to a file. You use control-D to terminate the input. I also used cat to display my environment.plist file. You can see the command that immediately precedes the text. But remember that you do have to edit the copy of my file to meet your needs. It is likely that you need only the PATH part but you should edit that so that the first directory, before the first separating colon, is the one that perl 5.10 is in. You probably don't want my personal bin directory but you might want to have a PERL5LIB directory which could also contain modules that would be found wherever perl came from. The /bin and /usr/bin items are pretty much required. cat, for instance, gets found that way. The file format is xml. Entries are in pairs of lines key defines the name and string declares the corresponding value. You might well have a text editor, bbedit or text wrangler (its free cousin) come to mind, that would have no problems dealing with directories whose names start with a dot. That would be fine in place of unix tool cat. You could also use Apple's plist editor but I suspect it would confuse you more than it would help.

Re: Perl install problems OSX 10.4.11
Hi, Thanks for your excellent response, makes installing so easy assuming I did it correctly. I think everything that was required is installed, but I am not sure everything was installed in the right location. It appears that Perl 5.10.1 was installed and all the modules I installed are associated with Perl 5.10.1. When I try to run the get_iplayer PVR module I get the following error: Can't locate loadable object for module HTML::Parser in @INC (@INC contains: /opt/local/lib/perl5/5.8.8/darwin-2level (I have abbreviated the error message) And when I enter perl -v I get the following: This is perl, v5.8.8 built for darwin-2level So the system does not see the Perl 5.10.1 install. Can someone please tell me if there is a was to install the modules so they relate to perl, v5.8.8, or point get_iplayer to use Perl 5.10.1.

You'll be asked to configure CPAN the first time you run it; just take the defaults and you'll be fine. Then, once you get a cpan[1] command prompt, type the following: cpan[1] install LWP and hit enter. It will automatically figure out what prerequisites you need and download all the packages. Again, I generally take the defaults and everything works well. -packy

Can someone please tell me if there is a was to install the modules so they relate to perl, v5.8.8, or point get_iplayer to use Perl 5.10.1. I suspect that Apple's perl is 5.8.8 and it is installed in /usr/bin. It needs to stay there because Apple's updates may depend on it. Installing 5.10.1 in /usr/bin/ replacing 5.8.8 is not recommended. I also suspect that perl 5.10 is installed in /usr/local/bin but that might be different like /opt/bin depending on just how you installed it.. Look around for it. /opt/local/lib/ sounds unlikely to me. You are probably going to make a change to your PATH environment variable to make the directory that perl 5,10 resides in appear before /usr/bin. A shell command like: setenv PATH /usr/local/bin:$PATH # csh PATH=/usr/local/bin:$PATH # something like this in bash export PATH You can also specify PATH in a startup file $HOME/.MacOSX/environment.plist. but you'll have to create that including the .MacOSX directory unless it's already there. There are some instructions on Apple's web site. Ask if you'd like a sample. @INC is a perl array that lists directories in which modules can be found. There are a bunch of standard locations relative to the directory that perl itself lives in but you can add more directories by setting the PERL5LIB environment variable to a PATH-like list of other directories. That too can be done in environment.plist. It's a bit hard to understand why iplayer doesn't have an installation script or at least some less geeky instructions for users. -- -- A fair tax is one that you pay but I don't --

Hi, Thanks for replying Andrew. I don't fully understand what Perl does but if Perl comes installed with OSX it appears that I also have an install of Perl via MacPorts.

Terrence On 11 Sep 2009, at 20:32, Andrew Brosnan wrote: Don't remove your system Perl. Perl is designed to be extended with modules such as the ones you listed. They are normally installed as needed. Modules are available free via the CPAN at http://search.cpan.org/. Most perl programmers install them using the CPAN module or just via the command line. If you are not familiar with using the command line you may want to look at Fink http://www.finkproject.org/. Good luck!
