[Smtk-developers] Homebrew Python

[David Thompson]

> For those of you using homebrew python to build SMTK/CMB, be aware that "brew upgrade" will switch to python3, which causes build problems[1] at the moment.

If you already had a homebrew python2 built, a workaround is to "brew switch python 2.7.14" (or whatever version you have).

If you don't already have a homebrew python, I guess the workaround is to use the superbuild's python. But really we should get SMTK working with Python 3. I had it at least compiling a few months back but the ParaView python changes appear to have caused some configuration failures.
