 cpan2port port, but I have a feeling the solution isn't just to create
 that directory.

 called "perl5.major.minor" (not just "minor").

 Oh, I didn't realize that. I thought something C#-like was going on...

 > If there is to be a port for cpan2port (which is a good idea) it should
 just be called cpan2port. We do not need versions of cpan2port for each
 perl version, because cpan2port is not a perl module; it's just a program
 that happens to use perl.

 be installed. Am I missing something?

 No, it probably doesn't need the perl5 portgroup... I originally was going
 to try to do it without, but no one on irc had any ideas of a perl port
 that does'''n't''' use the perl5 portgroup that I could use as an example
 to work from, so instead I just used `portfile-gen` with the `-g perl5`
 flag set to give me a starting spot, as that seemed easier at the time...
