I thought that people didn't like PYTHONPATH.

Richard's local.pth suggestion works (without PYTHONPATH) on Fedora.  It 
seemed like an interesting approach.  So I started testing it.

Let me see if I can summarize:

We should always install
  main code to /usr/local/{bin,sbin}/
  python libraries in /usr/local/lib/pythonX,Y/site-packages/

If everybody agrees on that, then all we have to do is figure out how to make 
Python look there.

PYTHONPATH does that.  So does local.pth on Fedora.
