Sure. You can simply change the directory in which distutils looks for your
However, in general, you shouldn't be doing this. It's usually easier
(definitely in the long-term) to keep your sources cross-Py2.x/3.x
compatible, maybe with the help of tools like "six" or "python-future",
than to try to keep separate source trees in sync.
