M2Crypto uses still python setup.py test for calling its test suite. When I tried to switch to python -munittest discover -v I get this error:

[ 25s] + PYTHONDONTWRITEBYTECODE=1
[ 25s] + python3 -m unittest discover -s tests -v

The binary module is certainly in the directory included in sys.path, but that is apparently not enough. Is there some other variable I need to set ($PYTHONCPATH or something)? How are binary modules located?
