Sorry, I should have been clearer in that I'm using clang with libc++
(current Xcode version, 4.6.2), as this is now standard on OS X and
required by our software framework.  I posted the output of my build
failure above, which shows exactly what commands I'm using, but I'll list
my config here as well.

I have the following in my user-config.jam:

using clang : osx
: xcrun clang -stdlib=libc++ -std=c++11
;

To just build context, I do:

./bootstrap.sh --with-libraries=context
./b2 -a toolset=clang-osx link=static threading=multi stage

(added threading=multi to match your commands, I get the same result
without)

and immediately the output is:

lang-darwin.compile.c++
bin.v2/libs/context/build/clang-darwin-osx/release/link-static/threading-multi/unsupported.o
libs/context/src/unsupported.cpp:7:2: error: "platform not supported"

Thanks for looking at this...
