The entire point of PYTHONPATH is to be able to put things at the 
front of it, so I don't see how that's breaking anything.

When you ask easy_install to install something as the default 
importable version of that package, the only way to ensure that is by 
placing that thing at the front of sys.path, to override any other 
version of it that might be installed elsewhere on sys.path.

Well, the only way short of going through all of sys.path and 
deleting anything that might potentially be in the way.  That 
approach was tried in I think the 0.4 line of setuptools, however, 
and it wasn't very popular.  :)
