An easy way to get reverse dependencies is to use cpangraph. You'd run it like this:

cpangraph --reverse CGI
[download]

It'll produce a svg graph in the current directory. Use your browser to view it. Now, to get to the point where you can run that command, you'll need to install CPANDB::Generator. Then run this:

#!/usr/bin/perl

use strict;
use warnings;
use CPANDB::Generator;

my $cpan = CPANDB::Generator->new(
         cpan  => '/root/.cpan',
         sqlite => '/root/CPANDB.sqlite',
)->run;
[download]

That will fetch the sqlite database necessary to get the dependencies. It'll take time, so be patient. Next, make sure that your system can handle svg. Here's a bundle that I used, and, trust me, it works. The whole process will take a couple of hours, so hang tight. Then you're good to go.

#!/usr/bin/perl

use strict;
use warnings;
use CPAN;

CPAN::Shell->force('install',
