OK, then the figure I gave should be pretty close. I counted packages using a "perl-" prefix in Fedora's package database. As most CPAN dists in Fedora are packaged into separate rpms prefixed with "perl-" this should give a pretty good estimate. > > I really have no idea how a distro can be claimed to be supporting > 8000+ > > perl-dists, nor how useful such a distro would be.

To put it bluntly: Perl-dists in Fedora are more or less community-only maintained, i.e. inclusion of perl-dists in Fedora is more or less community demand-driven => There is little demand for these remaining 12000 packages, probably because hardly anybody needs them. > > > What if you could have a "wishlist" that you could present to > CPAN module > > > authors?

Example: A perl-dist using a version number of 0.04. What does this mean? For rpm, 0.04 equals 0.4. For CPAN this means something completely different. This raises version comparison problems when perl-dists jump in their versions, e.g. 0.04 -> 0.40. For rpm, both versions are equal = 0.4 ("null point four"), i.e. CPAN/Perl versions need special treatment when mapping them to rpm versions. > > - Think about the licenses you apply.

Most CPAN dists apparently are maintained by individuals, who actually don't care much about licensing. There are CPAN maintainers who switch from GPL to MIT though their dists contain loads of user-contributed code. There are CPAN packages which don't have any license information inside. There are CPAN packages harvesting code from other packages without thinking about licenses at all ... You might not be aware about it, but there are people who considers the original "Artistic" license to be non-free (One of these groups is the FSF: http://www.gnu.org/licenses/license-list.html) > > - Write better code.

IMHO, the fact Fedora, Debian, Ubuntu etc. are getting away by not shipping 12000+ modules speaks for itself: Most of CPAN is more or less dead code, for various reasons. One reason is modules not making it into mainstream distros due to lack of quality. Licensing issues, lack of generality and lack of portability are other reasons.
