Something like this:

#!/usr/bin/perl

use strict;
use warnings;

use ExtUtils::Installed;

my $inst = new ExtUtils::Installed;
foreach my $module ( sort $inst->modules() ) {
    my $version = $inst->version($module) || '**unknown**';

    print "$module version $version\n";
}

Which in all probability I found posted here in the first place.
