CPAN modules used by non-CPAN packages

[Gabor Szabo <szabgab@gmail.com>]

Hi,

so the http://ali.as/top100/ lists the top 100 modules that are used
by the biggest number of other things in CPAN.

It does not take in account anything that is not on CPAN.

I'd like to provide some improvement to this by collecting
the dependency information from Debian.
I'd like to gather the list of packages that use CPAN modules.

How can I do that?

e.g. Bugzilla is packaged by Debian
How can I list all the modules it uses ?

In the opposite direction given a CPAN module
how can I find all the Debian packages
depending on that package?
