This is an interesting point that we are just facing. If you have a big 
package for all your stuff and you want to separately version components 
of it, you do run into problems. The solution we are adopting is to 
write a custom import hook, but a simpler solution is to make sure each 
separately versioned component is a top-level package (in which case you 
can manipulate PYTHONPATH to temporarily "install" a test version).
