creating my own module search path

[Sean 'Shaleh' Perry]

so, like a good little coder I use functions for code reusability and ease of
maintenance.  I have a directory structure like:

./
  frontend/
  lib/
  ...

I would like to be able to load files in lib as python modules.  I know how
to add the directory to sys.path.  The problem is I have a module named
'util.py'.  Sure, I could rename it.  But I can not possibly know the name of
every module on a user's system.  What I was trying to do was add the path
just before lib to the search path and load it as 'lib.util'.  But this does not
work.  Suggestions anyone?
