vispy segfault

You never remember the difference between computers. Vispy wasn't working.

degs:vispi% python line-draw.py
zsh: segmentation fault  python line-draw.py

This doesn't give you much to go on. After diving into the debugger, I found that I had a bad binding from Python into the Qt5 library. I fixed it with:

sudo port install Qt5
pip install PyQt5
