And we got fooled again by running installed tests instead of local ones for half an hour. Putting this to confirmed. If there is really no way around the make install it should happen automagically, either by allowing make autopilot to filter for a single test case or calling make install from within the __init__.py.

And the fallback to the installed one really needs to go if there is the slightest indication that a local (non-installed) test suite is ran.
