The problem is that you didn't configure and install Python such that
it generated a shared library for Python. Nothing to do with
mod_python.

For details see section 'Lack Of Python Shared Library' of:

  http://code.google.com/p/modwsgi/wiki/InstallationIssues

This is for mod_wsgi (which performs better again than mod_python for
WSGI hosting), but still relevant.

So, fix your Python installation. That is all you should need to do.
