If you know that you're 'use'ing all your modules at the beginning and
don't load any modules during the execution using 'require' and
'import', then it should be sufficient to dump %INC.

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

Of course in this case they are all core modules, but you could filter
that list by looking for 'site_perl' in the path.
PS: I've made the mistake to install quite a handful of modules via
Debian packages instead of CPAN and they are *NOT* installed in
'site_perl' but somewhere in '/usr/local/share' and are also *NOT*
registered in perllocal. That's *NOT* funny, Debians!
I've not verified this, but I guess that could be a problem with other
Linux distros too.
