FWIW, I recently upgraded an older MacBook to Mac OS X 10.7.5 and there are 3 
different versions of Python in /System/Library/Frameworks/Python.framework, 
see:

$ ls /System/Library/Frameworks/Python.framework/Versions/
2.5     2.6     2.7     Current


It is unclear whether MacOS X 10.7.5 installed all four of these Python 
versions.  The older one(s) may be left over from the previous MacOS X release 
on the machine.  But all are Apple builds of the Python version, for example:

$ python2.7
Python 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D


In addition, there is a link in /usr/bin to the python2.X, pythonw2.X and 
python2.X-config file for each version, see

$ ls -la /usr/bin/python*

Perhaps you can reinstall these Pythons from the CD which came with the Mac.  
Let me know if you need  more info.
