Assuming what you want is possible, (and it has to be, right?)  I am
sure there are a few ways to make it work, some better than others.

What comes to mind: are you familiar with virtualenv?

I think that will help get all your versions aligned.

Even if it is of no help to this problem, all python developers should
be familiar with it.
