 > Both of these where unable to build this root6 update (Sorry, I cannot
 recall if the issue was specifically with the internal clang build, or
 root itself). It could also be due to the fact I wish to enable C++14
 support with this update.

 Based on http://clang.llvm.org/cxx_status.html, it looks like llvm 3.4 and
 later support C++14, so I'd expect Xcode 6.2 to work for you as well as
 macports-clang-3.4.  I wonder what the issue is.

 And that only refers to very recent (within the past month) llvm trunk.
 Hopefully you're using more mature sources than that ;).

 whats report when it configures the build, I don't know exactly what
 tag/revision etc. they are using).

 Then you don't need to worry about tsan.  That just landed in master a few
 weeks ago.

 I'd suggest making it a variant that is on by default if Xcode 6.3 (?) or
 later is installed.
