I don't know.  When I used get_iplayer I chose not to use its installer, 
but
to install my own distribution of perl and then the extra modules it 
needed,
so as to be "in charge" of perl on my own machine.

Otherwise if I'd wanted to use perl for anything else I'd have needed to 
have
"my perl" and the g_ip one separately installed (so that the latter 
could be
changed when g_ip needed it, without impacting on my own one).

After doing the perl install and checking it had worked, which I did by
issuing

   perl -h

from a normal windows command window, which produced sensible output, I
then did

  cpan App::cpanminus

which uses the "cpan" command to get a module from http://www.cpan.org/
(the Comprehensive Perl Archive Network).  I'd read somewhere that
"cpanminus" is a wrapper for cpan which makes "cpan" easier to use, but
clearly had to use "cpan" to get that.

Issuing such a command basically attempts to fech, install and test a
module.

For me, with perl installed at a system level for every user, with eg
perl binary folders placed on PATH, this worked.  It might be trickier
if the g_ip version of perl isn't pathed.  Perhaps you can run the
equivalent commands by CD into one of the perl directories and then
run commands from there?


I then issued cpanm commands for every module I knew I used (IIRC there
was a list of them in the g_ip install notes for people not using the
installers).  So for example:

C:\>cpanm Authen::SASL
Authen::SASL is up to date. (2.16)

would show me that an attempt to install the most recent version of
Authen::SASL   was unneeded because I already had it, whereas an
earlier attempt (on a different machine)


C:\>cpanm Authen::SASL

For that one, I've no idea why the download failed, but I subsequently 
grabbed the file
with a browser then used


C:\>cpanm "C:\Documents and Settings\XXX\My 
Documents\Downloads\Authen-SASL-2.16.tar.gz"

I don't know if that's helpful.
