It does and it doesn't. The 2.3 version can't be run as command line
instance and bits are missing such that you cannot even compile
against it for an embedded system. It is only of use where you have
brought an embedded system binary from Tiger which was compiled
against it on Tiger.

Thus, 2.3 on Leopard should be completely ignored. That you were even
mentioning it made me wrongly thing you had done something wrong with
your system. That is, so completely ignore 2.3 on Leopard that I had
forgot it was there.

Tiger and Leopard.

$ python -V
Python 2.5.1

For Leopard.

$ ls -las py*
8 lrwxr-xr-x  1 root  wheel  71 16 Nov  2007 pydoc ->
../../System/Library/Frameworks/Python.framework/Versions/2.5/bin/pydoc
8 lrwxr-xr-x  1 root  wheel  74 16 Nov  2007 pydoc2.5 ->
../../System/Library/Frameworks/Python.framework/Versions/2.5/bin/pydoc2.5
8 lrwxr-xr-x  1 root  wheel  72 16 Nov  2007 python ->

8 lrwxr-xr-x  1 root  wheel  82 16 Nov  2007 python2.5-config ->

8 lrwxr-xr-x  1 root  wheel  76 16 Nov  2007 pythonw2.5 ->
../../System/Library/Frameworks/Python.framework/Versions/2.5/bin/pythonw2.5

This is all likely going to be the same as you have.

More importantly, what do you have for:

$ cd /System/Library/Frameworks/Python.framework/Versions

$ ls -las
total 8
0 drwxr-xr-x   5 root  wheel  170 16 Nov  2007 .
0 drwxr-xr-x   7 root  wheel  238  9 Nov 21:48 ..
0 drwxr-xr-x   7 root  wheel  238 16 Nov  2007 2.3
0 drwxr-xr-x  11 root  wheel  374 21 Feb 14:27 2.5
8 lrwxr-xr-x   1 root  wheel    3 16 Nov  2007 Current -> 2.5

If that Current link has been changed then it will pick up wrong
framework at run time and cause lots of problems.

In all, I probably think the problem is that you hand doctored
makefiles to get anything to work on Leopard and got it wong. For
example, the following is wrong:

 -framework Python
-Wl,-F/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5

So, rather than try and fudge things yourself, just check out latest
version of mod_python from subversion repository.

  svn co https://svn.apache.org/repos/asf/quetzalcoatl/mod_python/trunk
mod_python-trunk

and use it as it has fixes to work on Leopard.

If you don't actually need features of mod_python and just want to
host Django, Trac or some other WSGI capable application, use mod_wsgi
instead.

BTW, please use reply-all and keep followups on list.
