geekondemand has asked for the wisdom of the Perl Monks concerning the following question:

I'm faced with moving a fairly large application that uses lots of CPAN modules to a new box. Is there a way to get a listing of installed modules on each box so that I can determine what needs to be installed? I'm looking for pointers toward writing a script that walks the perl directories or a feature in cpan that I'm missing. This is on redhat linux.
