[mod_python] Upgrading 3.2.10 -> 3.3.1

If you have installed multiple versions of Python installed in
different locations then you must ensure that PATH environment
variable of Apache when it starts up finds in that PATH the version
you want first. It doesn't actually run it, but Python internal
initialisation uses it as a reference point to determine where Python
lib directory is located.
