[coming out of lurking on this one]

It looks like, when run from a python script in GRASS, you're getting  
the system python.

Yet, when you run python itself from GRASS, you get the python.org  
Python.  What is the shebang line (first line) in your python script,  
it may be pointing to the system python?

/usr/bin/python should be a symlink to the SYSTEM python.
