I don't get what you're saying:
1) "I can use a package if I set PYTHONPATH to ~/nix-profile/lib/python2.7/site-packages/packagename.egg"

2) "I tried just setting the path to the site-packages directory
  [..] but doesn't seem to work"

You know that you can pass multiple paths separated by :?
eg PYTHONPATH=a:b:c where a,b,c are paths to packages?

Also google for PYTHONUSERBASE.

In the past I felt running into .pth realted trouble, but probabli this
all is gone.
