Never!  As the tests fail and problems are identified, I edit the sources,
and redo the setup.py install on one or more of the Python versions.

Me too.  Iterative and incremental is highly productive.

I haven't even looked for such a way, since going to site-packages is
no problem for me.  If I was developing on a Python installation shared
by several users I'd no doubt feel differently about it.

Many things are.  Fortunately, cvs, for all of its problem, doesn't do the
readonly thing:-).
