I can't replicate this failure. Can you give us some more information about what conditions you're seeing the failure under?

Okay, the original report happened when running pytest.

Using the new unittest way I see

#!python

python -m unittest discover -p "unittest*.py" --verbose
....

The whole thing is when I am running the test suite during installation on a Gentoo Linux system.

Can you check that six is installed correctly for the Python interpreter you're using? If it is, try running:

from six.moves import http_client
http_client.HTTPSConnection

and describe what happens.
