CPAN modules used by non-CPAN packages

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?

I too wonder if there is a 'proper' way to go from perl module name to deb

as in my Foswiki extensions debian build script, I do some pretty
simplistic looking using apt-cache, and then have a hand added list for
those I notice don't get found magically.


( resulting in http://fosiki.org/Foswiki_debian )

#try to convert from Perl name to debian name
#then test for availability?
my $pkgname = 'lib' . lc($depName);
$pkgname =~ s/::/-/g;
my $cmd = 'apt-cache search ' . $pkgname . ' | grep perl';

#print "DEPENDENCIES: ====== $cmd \n";
my @pkgs = `$cmd`;

#print " $pkgname found : ".join('; ', @pkgs)."\n";
if ( ( scalar(@pkgs) == 1 )
&& ( defined( $pkgs[0] ) )
&& ( $pkgs[0] ne '' ) )
{
$pkgs[0] =~ s/^(\S*)\s.*$/$1/;
$pkgs[0] =~ s/\n//;
