Import error with wsgi and Django

[Jer]

Hello,
I just recently put modwsgi on both my personal and production
servers, both servers are running Fedora Core 7 w/Apache2.

I have the same basic setup between the two servers, however I'm
running into an odd issue with the production server and modwsgi. I
get the following error in the apache logs when trying to hit the
site:

[Mon Feb 08 10:40:30 2010] [error] [client 208.247.xx.xxx] mod_wsgi
(pid=24538): Exception occurred processing WSGI script '/

ImproperlyConfigured: Error importing middleware
django.contrib.flatpages.middleware: "No module named mysql.base",
referer: http://mysite.com/standards/

If I uncomment LoadModule python_module modules/mod_python.so then I
don't get the error and the site loads.

Here is the apache config:

#LoadModule python_module modules/mod_python.so
LoadModule php5_module modules/libphp5.so
AddHandler php5-script php
LoadModule wsgi_module modules/mod_wsgi.so

<VirtualHost *>
ServerName mysite.com
WSGIScriptAlias / /django_projects/thesite/django.wsgi
</VirtualHost>
<Directory /django_projects/thesite/>
Order deny,allow
Allow from all
</Directory>

and my django.wgsi file:

import os
import sys
os.environ['PYTHON_EGG_CACHE'] = '/python-egg-cache'
os.environ['DJANGO_SETTINGS_MODULE'] = 'thesite.settings'

sys.path.append('/django_projects')
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Any help would be appreciated. If you need information/I left anything
out, please let me know.

Thanks,
Jer

Likely that your mod_python was compiled against a different Python
version for which mysql wasn't installed, or it used a static Python
library and not a shared library. Such mismatches can causes crashes,
strange behaviour or outright failure. Have a read about this conflict
between mod_python and mod_wsgi in:
