Am running into a build problem on Mac.

One thing that is different is that Xcode 7.3.1 force installed itself last week so this morning I reinstalled 6.2 and copied the 10.9 SDK into the 7.3.1 SDK directory as per this info: http://blog.felix-schwarz.org/post/141482111524/how-to-use-the-os-x-109-sdk-with-xcode-73 Then I reconfigured using --with-sdk-name=macosx10.9 (no errors reported), ran make clean, and make images and got the above report.
