Two different python paths in showing up Django

I see two different python paths in django.

This one shows up with the development server(i.e. python manage.py runserver etc.):

    ['/var/www/html/django/congressticketing', 
'/usr/lib/python2.4/site-packages/MySQL_python-1.2.3c1-py2.4-linux-i686.egg', '/usr/lib/python2.4/site-packages/pisa-3.0.32-py2.4.egg',

This one - much shorter - shows up in production(using mod_python):

    ['/var/www/html/django/congressticketing',

'/usr/lib/python2.4/site-packages/Numeric', 
'/usr/lib/python2.4/site-packages/PIL', 
'/usr/lib/python2.4/site-packages/gtk-2.0']

Does anyone have any idea why this is?

It could be a permissions problem. Check the file and directory permissions on the missing site-packages. It could be that those files are not accessible to the user name under which mod_python or Apache is running.
