how can we deal with that? I don't own a Mac, so I can't test it. I assume it's caused by some configure quirks, e.g. in context/build/Jamfile.v2 evaluates ../../config/checks//cxx11_hdr_mutex. depending on the result of this check, boost.thread is linked or not.

It seems that it doesn’t link to boost::system which is required for boost::thread.
