[GNC] Python Error

[Robin Chattopadhyay]

I did not try removing the previous versions, the only one on this VM is
4.4.

I removed both 4.4 and 4.6 then rebuilt 4.6 and that didn't change anything
BUT I did figure out based on your suggestion that the engine was looking
at the libraries at /usr/lib/python3/dist-packages/. Once I updated the
PYTHONPATH variable to look at  /usr/local/lib/python3/dist-packages/
instead it started working again.

Thanks!
Robin
