[mod_python] ImportError: No module named linecache

If you do have multiple Python versions, read:

  https://issues.apache.org/jira/browse/MODPYTHON-225

Also run the command line python executable for the version you expect
to be able to use and go:

  import mod_python

If it doesn't find the module, then Python component parts of
mod_python not installed for that version.
