thanks for your answer.
I'm using Puthon 2.7 for the given project and there sys.meta_path is .
Just for fun I started Python3.3 and looked at it's meta_path, which
contained for example _frozen_importlib.PathFinder
Unfortunately python 2.7 does not seem to have the package _frozen_importlib
So now the question seems to boil down to looking for the 2.7 equivalent
of python 3.3's _frozen_importlib.PathFinder
