Handling of multiple Pythons on the same system

[Kirk Strauser]

How do you manage multiple versions of Python on the same machine?

I'm running Zope on one of my servers and it requires Python 2.1 (and has
known issues with later versions).  I want to install other applications
that require Python 2.3.  I've installed the lang/python (2.3) and
lang/python21 ports and everything is basically OK.

Except, now, that I want to use the databases/py-psycopg port with both
versions of Python.  Whenever I build the port, I get either:

    py21-psycopg-1.1.7

or

    py23-psycopg-1.1.7

depending on whether /usr/local/bin/python is a link to python2.1 or
python2.3 at the port's build time.  Those packages are mutually exclusive;
they both write some files to the same place, and write other files to
version-specific paths.

This is quickly becoming a hassle.  Is there a good workaround for this
situation?
