Errors on Python 3.4 and Python 3.5, but not 2.7.
Investigation by TC at the time at : https://gitter.im/matplotlib/matplotlib?at=58457e49b4ffd59e38ea84c8, further pointing to http://bugs.python.org/issue26844 , but this is a patch to fix the error message, to make it more informative.
I couldn't reproduce the error on my local desktop, running OSX 10.11.
Thoughts:
- travis recently replaced its OSX default runtime; need to replicate OSX / xcode version for last successful build, to see if it could be an infrastructure change;
- investigate dependencies. TC mentioned namespace packages - @tacaswell - was that from some further investigation you did?
