"Fatal Python Error" Need Help

[Yogesh Gupta]

Hello,

I am trying to run a python based program on MacOSX, which needs following
packages

numpy
PIL
matplotlib

I can successfully import all 3 using python2.5 (only using /sw64/bin/python
or /sw64/bin/python2.5) , although i have python2.6 and 2.7 installed. I get
following error when in run executable:

*"Fatal Python error: Interpreter not initialized (version mismatch?)
Abort trap*"

Seems like a correct python version needs to be defined somewhere, that i am
unable to find.

Some details about location of various pythons are as follows (i have not
specified a python path in my .bashrc or .bash_profile):

*$which python*
/sw64/bin/python

Could someone point me to a solution?

Thanks so much for your time.
