Just drop support for 10.6 with Python 3.4. Problem solved. People on that old of a version of the OS can build their own Python 3.4 or do the right thing and upgrade or just install Linux.

This isn't Windows. Compiler tool chains are freely available for the legacy platform. We don't need to maintain such a long legacy support tail there ourselves.

Honestly, a separate 10.6 build would work well. Plus, if a new Clang versions includes some awesome feature that could make Python builds better, you'd be able to take advantage of it better.

Could go the Sage route -- Sage first checks for an up-to-date version
of gcc, and downloads it and builds it for its own use if necessary.
