Comment (by pmav99):

 That being said, even after applying the patch the testrunner is still not
 running as expected. More specifically all the tests are failing with this
 message on `stderr.txt`:

 {{{
 .../stderr.txt
 Unknown option: -3
 usage: python3 [option] ... [-c cmd | -m mod | file | -] [arg] ...
 Try `python -h' for more information.
 }}}

 Python 2 does indeed have a `-3` switch but Python 3 does not. I am
 looking but I can't find where this switch is added. If anyone has any
 idea, please post.
