 Replying to [comment:17 jonesc@…]:
 > Maybe I am mis understanding the above, but is the issue just the build
 cannot be done in parallel?

 No, it throws a compiler error (independent of the number of cores
 involved).

 > If so, is another possible work around just to force a non-parallel
 build on OSX 10.6 ?

 I don't think so. I was running both `"make"` which uses a single process
 as well as manually executing single commands, one-by-one. I think that
 `TMCtls.h` really has a bug. One cannot draw conclusions that `__thread`
 is supported just because `clang` is being used.

 But it might be related to #43989 for example.

 So basically now we are at:
   * a trivial bug in `clang-3.4` header files (up to Jeremy to fix)
   * a bug in `montecarlo/vmc/inc/TMCtls.h` (trivial to patch even if
 upstream ignores us)
   * the issue with CMake automatically adding `-isysroot` flags (probably
 the most problematic one at the moment unless Pere can help us out)
   * (other problems yet to surface)

 Currently I'm stuck with X libraries not being found.
