Thank you Graham for the immediate response.
Sorry I could not reply immediately.
I have actually figured the solution and fell asleep (work in a different time zone).
I missed to mention the following facts: -
1. I have two different users for each of the Python versions
2. One user runs on Python 2.5.1 and another user on Python 2.3.5
3. I run Mac OSX 10.5.6 with latest updates
4. For each of the users the default python PATHS are setup so that each gets his/her own version of python at command prompt
Changes I made to make Python 2.5 and 2.3 co-exist without interfering with each other
------------------------------------------------------------------------------------------------------------
1. I modified the symlink /System/Library/Frameworks/Python/Versions/Current point to 2.5
2. Then redid the following
./configure --with-ptyhon=/usr/bin/python2.5
Modified the paths in Makefile to point to Python2.5
Added '-arch i386' options wherever required in the Makefile
make && sudo make install
www:src Tool$ otool -L mod_python.so
> mod_python.so:
> /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.3)
> /System/Library/Frameworks/Python.framework/Versions/2.5/Python (compatibility version 2.5.0, current version 2.5.1)
> /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
> www:src Tool$ file mod_python.so
> mod_python.so: Mach-O bundle i386
I have reset the symlink Current to 2.3.
Note
-------
1. Looks like the symlink '/System/Library/Frameworks/Python/Versions/Current ' plays a very important role up to creating the mod_python.so.
2. Now I am able to run the python web-apps from any login irrespective of which python version access is provided to
INFERENCES (please validate these)
---------------------------------------------------------
1. Web-based python does not include command-prompt based python
2. All python web-apps refer only to mod_python
3. Command prompt Python refers to the PATH variable in the Shell's ENV variables whereas mod_python refers to its own internal path settings for python version (which probably got create during the 'Configure and Make')
3. Mod-python uses the python settings provided during the "./configure --with-python=" and the settings provided in the python paths of Makefile
4. Specifying Architecture is an important component for creating a workable mod_python
Regards,
Eeswar

Subject: Re: [mod_python] mod_python: How-to Resolve Python Version conflicts
You may well have screwed up your operating system Python
installation. You should never install separate Python versions under
/System/Library as that is reserved for operating system supplied
packages. You should also never change /usr/bin/python to put at some
other version because if operating system functions are dependent on
the version that was there previously, you will cause those bits of
the operating system to fail.
Since your operating system is now in such an unknown state of
functioning, there isn't probably much point trying to pursue why you
have problems.
Next time install the alternate Python under /Library or better still
/usr/local and don't stuff with /usr/bin/python. Then as per
instructions for mod_python, use the --with-python option to configure
script to say which version of Python you want to use rather than
trying to hand edit things as you likely aren't changing everything
that would need to be different when different Python version used.
