That's my guess too. In addition to Roger's suggestions, you can look on 
your system for multiple Pythons:

$ ls -l /usr/bin/python*
-rwxr-xr-x  2 root root 5568 Jun 13 13:41 /usr/bin/python
lrwxrwxrwx  1 root root    6 Jun 29 19:53 /usr/bin/python2 -> python
-rwxr-xr-x  2 root root 5568 Jun 13 13:41 /usr/bin/python2.4

$ ls -l /usr/local/bin/python*
ls: /usr/local/bin/python*: No such file or directory

So in my case, I have python2.4 installed in /usr/bin, and nothing in 
/usr/local. In /usr/bin, python and python2.4 are hard links to the same 
file, and /usr/bin/python2 is a soft link to it.

Those three are all there so that you can have multiple versions 
installed. "python" is the default version, and you can get the version 
you want by typing "python2.4" or "python2.3" on the command line.

I tend to put:

#!/usr/bin/env python2.4

on my #! lines, so that I'll be sure to get the one I want, and as a way 
to document which version the code was tested against.

It's possible you have a python somewhere else on your PATH, but those 
are the two most likely candidates.

To see what you are running:

$ which python
/usr/bin/python
