I'm not entirely clear on the need for all this version stuff
people keep talking about, but wouldn't the effect of the above
be about the same as using a .pth file in the appropriate place
for each different Python version on your machine?  Then you
can pick up different versions of different things at will
depending on which version of Python is run.

Having missed the discussion preceding, I'm probably off the mark,
but in my experience just about everything that can be solved with
PYTHONPATH can be handled with a .pth file as well, and I haven't
had any need to use PYTHONPATH for quite some time as a result.
