There are several options, including the PYTHONPATH environment
variable, creating a .pth file in site-packages or somewhere
(as documented in http://www.python.org/doc/2.4/lib/module-site.html),
or even creating your own sitecustomize.py file (also documented
in the site.py module docs).

What is best depends a bit on your own environment and needs.
For example, do you just want this available at the interactive
prompt, or to all code you write, or to code that other users
on the same system will write?
