Comment (by ryandesign@…):

 It might not be documented in the guide, but it is correct that you need
 to depend on a specific perl version. This is because you cannot know
 which variant of the perl5 port is installed, so you cannot know what
 version of perl the `perl` executable is. If you don't care, then you can
 just depend on bin:perl:perl5 and run `perl`, but if you do care (and if
 you need a specific perl module, then you have to care, because you have
 to install the perl module for the version of perl you're using), then you
 have to depend on port:perl5.16 or whatever version you decide, and p5.16
 -text-csv etc. and run `perl5.16` instead of `perl`. Yes, this means if
 the default version of perl in MacPorts changes, the port should be
 updated to match that, if possible. This doesn't happen very often,
 however.
