Are you sure you're searching in the right location? On OSX you 
should look in (kLocalDomain, kSharedLibrariesFolder), on OS9 in 
(kOnSystemDisk, kSharedLibrariesFolder). See ConfigurePython.py 
for details.

An alternative is to look for the preference file. 
pythonprefs.py has some of the details, but it picks up the 
actual name of the prefs file (which changes from release to 
release) from Python itself, so you'll have to fill that in by 
hand.
