Hey,

I think you need to make sure that clang is running with the '-std=c++11'
option, or that is added to your cxxflags somehow. I don't know if there is
a better way now, but to build with clang/libc++/C++11 on OS X I add the
following to tools/build/v2/user-config.jam:

using clang : osx
: xcrun clang -arch i386 -arch x86_64 -stdlib=libc++ -std=c++11
-fvisibility-inlines-hidden
;

and then run:

./b2 toolset=clang-osx
