Excuse me my ignorance, but why something like that is not already
working?  If Python-based installations automatically look in
lib/python2.6/site-packages/ under my home directory, why doesn't the
stand-alone installation do something similar?  It does include a DLL
that is the Python interpreter, doesn't it?
