Comment (by anonymous):

 marshall,

 Thank you, I've read about this on stackoverflow. I see two problems here:
 Firstly, switching to libc++ means that end-user will have to compile
 boost with libc++ interfaces instead of using binary packages. And
 secondly, not any C++11 code will compile against libc++ as is.

 I believe the problem can be solved with a few directives in
 {{{config/stdlib/libstdcpp3.hpp}}} like

 {{{
 // C++11 features in libstdc++ shipped with Apple Clang
 #if __APPLE__ && (__GNUC_LIBSTD__ <= 4) && (__GNUC_LIBSTD_MINOR__ <= 2)
 #  define BOOST_NO_CXX11_RVALUE_REFERENCES
 #endif
 }}}
