 Please could you try the following patch


 {{{
 #if defined( BOOST_NO_CXX11_NUMERIC_LIMITS )
 #define BOOST_CHRONO_LIB_CONSTEXPR
 #elif defined(_LIBCPP_VERSION) && _LIBCPP_VERSION <= 1101
   #define BOOST_CHRONO_LIB_CONSTEXPR
 #else
   #define BOOST_CHRONO_LIB_CONSTEXPR BOOST_CONSTEXPR
 #endif
 }}}
