Looks like there is same problem in F17:

fedora-release-17-1.noarch
python-2.7.3-7.2.fc17.x86_64
mod_python-3.3.1-17.fc17.x86_64

# service httpd restart
# tail /var/log/httpd/error_log | grep error
[Tue Aug 07 18:37:40 2012] [error] python_init: Python version mismatch, expected '2.7.2', found '2.7.3'.
[Tue Aug 07 18:37:40 2012] [error] python_init: Python executable found '/usr/bin/python'.

+++ This bug was initially created as a clone of Bug #844676 +++

Description of problem:

It looks like python 2.7.3 landed in Fedora 16 updates. This leads to error in Apache's error_log upon startup.

Version-Release number of selected component (if applicable):

# rpm -q python mod_python
python-2.7.3-3.fc16.x86_64
mod_python-3.3.1-16.fc16.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. Have Fedora 16 with httpd, python-2.7.2, and mod_python. Observe that there are no errors upon Apache start and the notice line says

[Tue Jul 31 10:17:08 2012] [notice] Apache/2.2.22 (Unix) DAV/2 mod_python/3.3.1 Python/2.7.2 configured -- resuming normal operations

2. Run yum upgrade python, note that version 2.7.3 gets installed.
3. Run service httpd restart, look into /var/log/httpd/error_log.
  
Actual results:

[Tue Jul 31 10:17:49 2012] [error] python_init: Python version mismatch, expected '2.7.2', found '2.7.3'.
[Tue Jul 31 10:17:49 2012] [error] python_init: Python executable found '/usr/bin/python'.
[Tue Jul 31 10:17:49 2012] [error] python_init: Python path being used '/usr/lib64/python27.zip:/usr/lib64/python2.7/:/usr/lib64/python2.7/plat-linux2:/usr/lib64/python2.7/lib-tk:/usr/lib64/python2.7/lib-old:/usr/lib64/python2.7/lib-dynload'.
[Tue Jul 31 10:17:49 2012] [notice] mod_python: Creating 4 session mutexes based on 256 max processes and 0 max threads.
[Tue Jul 31 10:17:49 2012] [notice] mod_python: using mutex_directory /tmp 
[Tue Jul 31 10:17:49 2012] [notice] Apache/2.2.22 (Unix) DAV/2 mod_python/3.3.1 Python/2.7.3 configured -- resuming normal operations

Expected results:

[Tue Jul 31 10:17:49 2012] [notice] Apache/2.2.22 (Unix) DAV/2 mod_python/3.3.1 Python/2.7.3 configured -- resuming normal operations

and no error lines.

This might or might not be a blocker for bug 833139.

This is printed by mod_python, it uses strcmp to compare runtime version and built version. I'm rebuilding mod_python now, it should help I think.
