Sorry if I was not clear the first time.

I sugggest you reconfirm with him.

Re-reading the emails I see a bunch of double negatives going around.

Well, I sorta hate to bring it up, but since you asked: PYTHONPATH.

Until yesterday, the PYTHONPATH stuff was well documented and had

Once again, I'd like to go beyond PYTHONGPATH, but you asked.

Once again, I think pip has the answer: edit the sys.path.
