>Description:
devel/boost-* hardcoded BJAM_ARGS in compiled.mk, there is no way to customize this arguments, thus cannot use c++11/libc++

>How-To-Repeat:
Build and install devel/boost-* ports, check /usr/local/lib/libboost_*.so, they are all linked to libstdc++ regardless what compilation/linking flags are set
>Fix:
Change devel/boost-all/compiled.mk, use "BJAM_ARGS += ..." instead of "BAJM_ARGS = ...", then we can effectively set "BJAMS_ARGS=..." in /etc/make.conf
