in reply to A master-list of module dependencies?
Is downloading every module really that much of a hassle? I maintain a local CPAN mirror on the Bioinformatics server up at school, and it's only 2.3G large. If size if really that much of an issue you could cut this down considerably by using merlyn's article on Mirroring your own mini-CPAN.
If I were doing this I would probably use a Mini-CPAN because you're probably not interested in older module versions.
