Then let's go patching.

Are you going to address other issues pointed out in this thread?


Also, what would you say about adding text like this to Porter's
Handbook?

The FreeBSD Ports Collection support parallel installation of multiple
Python versions. Ports should make sure to use a correct python
interpreter according to user settable PYTHON_VERSION variable.
This means, mostly, replacing the path to python executable in scripts
with value of PYTHON_CMD variable.

Ports that install files under pythonsitelibdir should use
PKGNAMEPREFIX=  ${PYTHON_PKGNAMEPREFIX}
so thier package name embeds the version of python they are installed
into.
