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.
Thanks,
Terrence

I think the problem is probably to do with my Perl install. I

HTML
HTTP
LWP
I have one machine here which is running 10.4.11 and, as you say,
it has Perl 5.8.6 and also is missing the modules you list above.
If it were me I would stick with the Apple install and, as Packy
Anderson has suggested, go to CPAN and download the missing modules.
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
I hate multiple versions of Perl, unless there is some compelling
reason for having a newer one, because of the confusion it can
cause. In the case of 'get_iplayer.pl', so far as I can see, there
is no reason to want any newer version of Perl than 5.8.6.
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.
Kind regards,
Alan

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.
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.
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'.)
Now 'get_iplayer.pl' starts with the 'shebang' "#!/usr/bin/perl".
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. I would be astonished if
any are missing in an Apple standard Perl install, but in that
unlikely event, I would think the simplest thing would be to
download the missing module from CPAN and pop it in. (On Mac OS X
10.4.* it might be 5.8.4 (?) I think, but that shouldn't matter
at all -- the script should be quite happy with that version).
The next thing to check is that /System/Library/Perl is listed in
@INC. Run the following in Terminal:
perl -e 'foreach (@INC) {print"$_\n"}'
In the unlikely event it is not in the list, then add it to @INC.
I hope these notes might be helpful to someone relatively unused
to Perl and apologise if I appear, so to speak, to be trying to
teach my grandmother to suck eggs...
