Heh. I guess what I really mean is: Is #2 a good idea, or would it be considered horrendously hacky? This is my itch, so I'm not afraid to be the one to code a solution, but I don't want to make things overall worse to fix one specific use case. >> If not, can 'make test' somehow hack out site-packages? > > > The problem is you're dealing with startup which means it won't come into > effect until it's too late. Yeah, but the 'make test' operation could set an environment variable or something to say "there are no site-packages, kthxbye". Again, there's currently no such facility, and probably that one is a bad idea, as it'd have implications (possibly security implications) for other runnings of Python. Steve's suggestion would keep all the visible hackery in test_site.py, and it's well known that tests often need to do dark and dangerous things.
