Like the suffix idea!
I just want to add, that it would be great to also automatically adjust 
DOCSDIR and EXAMPLESDIR with correct prefix to make docs/examples, 
installed by single port, but for different python version 
simultaneously. This will help to avoid conflicts.

Right now we have this (py-gnupg is just random python port):
# make -V DOCSDIR /usr/ports/security/py-gnupg
/usr/local/share/doc/gnupg

So right now it ever may conflict with gnupg docs, if I understand 
correctly. I think that correct dirname would be:
/usr/local/share/doc/py27-gnupg for python 2.7
and
/usr/local/share/doc/py33-gnupg for python 3.3

The same for examples.
