Re: Perl install problems OSX 10.4.11
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. I assume that get_iplayer is looking at the preinstalled Perl but I am not sure. Although I am no expert, I have used the Terminal to install binaries before so i will give it a go.

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!

I have been told that the following are some of the files I need: Built-ins: use Fcntl use File::Copy use File::Path use File::stat use Getopt::Long use IO::File use IO::Handle use IO::Seekable use IO::Socket use POSIX use POSIX use Socket use Time::Local Ones that aren't in core AFAIK: use CGI use CGI::Cookie use HTML::Entities use HTTP::Cookies use HTTP::Headers use IPC::Open3 use LWP::ConnCache use LWP::UserAgent use URI use URI::Escape This is the first time I have had to get involved with Perl so any help would be much appreciated.

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.

The perl that comes installed with OS X is located at /usr/bin/ perl. If you've also installed perl from some other source (like MacPorts) then you might have another perl at some other location. I've taken a look at the iplayer source (available through http:// linuxcentre.net/getiplayer/) and it's definitely using the Perl that comes with OS X at /usr/bin/perl/ Although I am no expert, I have used the Terminal to install binaries before so i will give it a go. It's fairly simple. Type sudo perl -MCPAN -e shell At a Terminal prompt and enter in your password when prompted. 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
Re: Perl install problems OSX 10.4.11
Hi, Thank you for the very informative response Alan. I think the problem is probably to do with my Perl install. I looked in /System/Library/Perl/ but the Perl folder contained 5.8.6 not 5.8.8. I could not find any of the following: Fcntl HTML HTTP LWP I previously installed some applications using MacPorts, and it appears that there is an install of Perl 5.8.8 in /opt/local/bin/. Over the weekend still trying to solve the problem I also installed Perl 5.10.1 in an attempt to upgrade my system Perl install. That is in /usr/local/bin/. I also searched /usr/local/lib/perl5/5.10.1/ and /opt/local/lib/ perl5/5.8.8/ and it would appear that the MacPorts install is the most complete but I could not find an LWP directory or HTTP, and I was not sure where to look for URI. The HTML directory contained entities.pm, and headerParser.pm but no Cookies Is it possible to upgrade the system Perl install to a full version of Perl 5.8.8?

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. I am puzzled why the original poster is having problems with 'get_iplayer'. Out of curiosity I downloaded it and find it runs fine here on a standard Apple Perl install. Regrettably I have deleted the original post but I recollect the writer said he was not a frequent user of Perl? So I wondered if the following thoughts might be helpful. 'get_iplayer.pl' is just a 272KB script (272KB) which can be put anywhere convenient and there is excellent documentation for it on the download site. Just for starters it is convenient to park it on the desktop. The first thing to do is set the executable flag by the following line in Terminal.app chmod +x full_path_to_'get_iplayer' -- it being understood that the easiest way to get the full_path_to_'get_iplayer' is just to drag 'get-iplayer.pl from where it is on the Desktop into the Terminal window. 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. If it does not, then some investigation is called for. To do this it makes life very much easier if the hidden folders (containing Perl and its modules) are made visible. 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. (The process can be reversed by running the line again with the lower-case 'v' replaced by an upper-case 'V
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. Is it possible to add the Perl 5.10.1 path to the environment so i don't loose the MacPort option. I have reinstall Apple's developer tools from my system install disk.

Is it possible to upgrade the system Perl install to a full version of Perl 5.8.8? I don't think there is any such thing really -- one is always encountering scripts which use modules one hasn't got. Then it's off to CPAN to repair the omission.

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.

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.

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.

Help setting Perl path
Hi, I have Perl 5.8.8 installed by MacPorts and a CPAN install of 5.10.1. Is there a simple way switch between them hopefully from the Terminal, so I can use 5.10.1 when using get_iplayer and 5.8.8 for other programs. In a previous post, it was suggested that I create an environment.plist. Using the following instructions: mkdir $HOME/.MacOSX cat $HOME/.MacOSX/environment.plist ?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:/usr/bin:/bin:/sbin:/usr/sbin/string /dict /plist type CONTROL D I assume this method is not temporary, but when I restarted my system, there was no change to the version of Perl being used. And to be honest, I didn't really understand what I was being told to do. I know for many getting get_iplayer to work on there system has been relatively easy, but I just can't get all the needed modules installed in my Perl 5.8.8. Thanks, Terrence
