[Pythonmac-SIG] How to provide additions to python path such that all executions of a given python binary will see them?

[Kenneth McDonald]

Currently, I modify my python path through inclusion of a PYTHONPATH 
variable
in the .login file. However, I need to add a /local/python/packages 
directory
to the path in such a manner that all executions of the system python 
binary
see /local/python/packages. I was just wondering up the best (least 
hacky)
way of doing this might be.

Thanks,
