We could add a new dependency type (and associated functionality) to allow ports to still depend on perl modules, and the perl5 port could uninstall/reinstall all of the installed perl modules when upgraded (or actually, on post-activate). 

If we don’t have a portfile for each CPAN module, how would we:

* not update to a newer available version if that version did not build on OS X?
* apply patches?
* blacklist a compiler?
* add a flag to CFLAGS?
* check the license to check if a dependent is distributable?

It seems like each of these would require special workarounds, which are not needed with the current way of creating a portfile for each package.
