Comment (by michaelld):

 I've done a -lot- of playing around with the default compiler on OSX
 10.9.5, which is Xcode 6.2 (6C131e) "Apple LLVM version 6.0
 (clang-600.0.57) (based on LLVM 3.5svn)". I'm pretty convinced that it
 can't handle the C++11 `std::initializer_list` parsing required by the
 code. MacPorts Clang 3.7 builds this code just fine; it's the oldest I
 have installed right now. As soon as the updates are complete I'll install
 clang-3.4 and clang-3.5 to see if either of those work -- guessing 3.4
 won't, but 3.5 might.

 Anyway, my current believe of our best solution here is to just blacklist
 this compiler on older OSX (e.g., "clang < 3.7") or however we phrase it.
 By now, most of the older OSX will have mulitple modern compilers
 installed already, so I don't see this as a deal-breaker -- at least so
 long as we can disable testing to bootstrap cmake using the Xcode-provided
 compiler ... not sure we do that right now for when bootstrapping ... hmmm
 ... have to look into disabling testing for when we're doing that.
