[Boost-build] using "using" to make separate toolset configurations

Subject: [Boost-build] using "using" to make separate toolset configurations

in my user-config.jam file I have:

using darwin : 03 : /hpc-5.1/usr/local/bin/g++ : <cxxflags>"-std=c++03" ;
using darwin : 11 : /hpc-5.1/usr/local/bin/g++ : <cxxflags>"-std=c++11" ;
using darwin : 14 : /hpc-5.1/usr/local/bin/g++ : <cxxflags>"-std=c++14" ;
using clang : 03 : : <cxxflags>"-std=c++03" 
<cxxflags>"-Wno-c++11-extensions" ;
using clang : 11 : : <cxxflags>"-std=c++11" ;
using clang : 14 : : <cxxflags>"-std=c++14" ;

my intention is to be able to use

../../../tools/library_status/library_test.sh -j4 toolset=darwin-11 
variant=debug link=static >b2.log  &

../../../tools/library_status/library_test.sh -j4 toolset=darwin-11 
variant=debug link=static >b2.log &

etc.

But when run

../../../tools/library_status/library_test.sh -j4 toolset=darwin-03 
variant=debug link=static test_array_xml_warchive  >b2.log  &

I get

on the other hand, when I invoke

../../../tools/library_status/library_test.sh -j4 toolset=darwin-11 
variant=debug link=static test_array_xml_warchive >b2.log &

things work just fine.  What do I have to do to make this work.

PS

The reason I want to do this is so that I maintain different results for 
gcc with different versions of the standard library.  If I don't do this 
I only have the most recent one all with the same name.  This inhibits 
the library_status program from functioning as desired.

PPS - it seemed that this worked before but now it broke.
