Aye, I found it now.

Well, after some old SF movies & some sleep, I realized that :) But it is
going to have to change: you now have to include the build tree as well, and
that is quite a bit more difficult to figure out. I'd suggest a 'make run'
that calls python with the appropriate PYTHONPATH environment variable, but
that doesn't cover test-scripts (which I use a lot myself.)
