It's not unreasonable to ask people to add src to their PYTHONPATH by 
some means (pth file or otherwise).  Requiring this simple step, common 
to just about every other sane Python package, eliminates the need for 
a distributed autopath entirely.

As Michael has mentioned, it makes sense to have a module that cleans 
sys.path so that you don't have anything crazy in there, but autopath 
as implemented seems like quite an unnecessary hack to me.

I've just committed a smarter implementation that deals with symlinks 
and such more gracefully.
