Location of global libraries for Python on Mac?
Try checking your python's sys.path list with:
import sysprint(sys.path)
A simple method I use is to ask a module where it is:
import osprint(os.__file__)
/Library/Python/2.6/site-packages/ is indeed the right place (assuming it's Mac OS 10.6 "Snow Leopard" - you didn't mention which).
As @diatoid mentioned, check your system path (and make sure you're actually using Python 2.6 by running python -V).
