Thanks, that explains the behavior and solves all my problems. I will hold
my Dlls in a subfolder of my module, called 'DLLs'. In my __init__.py I will
do something like this:

import sys,os
from os.path import split, join
path = join(split(__file__)[0],'DLLs')
sys.path.append(path)
os.environ['PATH'] += ";"+path

Is that ok, or is there something bad with modifying sys.path and
os.environ['PATH'] in an __init__.py?
