I first wanted to make sure this was a new problem before I posted a bug 
report, as the cmake website asks. 

Welcome to the lists!

once and the eventual result is a fatal Python error due to mismatched 
libraries.

There are some known issues with Homebrew:

But it would be worthwhile trying CMake Git master:

Hope this helps,
