You should be able to test that by doing:

>>> import scipy
>>> import scipy.linalg
>>> scipy.linalg
>>> scipy.linalg
<module 'scipy.linalg' from '/usr/lib/python2.5/site-packages/scipy/linalg/__init__.pyc'>
>>> scipy.linalg.eig
<function eig at 0x8379c34>

See if the "module ..." and "function ..." output is the same on both 
setups .  If the module information (esp. the filename!) is different, yo 
uknow you're in a situation like Fernando guessed you were.

(For me, between loads, the function address stays the same, but that's a 
pretty poor indicator and I'm just mentioning in case it happens to be 
helpful.  Rely on the module's declared filename.)
