This would be an appropriate time I suppose to say I am attempting to build
numpy, scipy and matplotlib on 10.9.  NDA of course prohibits me
(unfortunately) from really discussing things but safe to say I would
support "moving on".  There are a multitude of issues that would be
resolved by dropping support for PPC (build complexity) and supporting SDKs
versions > 10.6.
