I think John is saying you can use -DBOOST_NO_CXX11_ALLOCATOR in your 
compiler command line when you compile your code.  I.e.code that uses 
boost, as a workaround until a fix to boost.config is available.  That 
way you do not have to wait.

If your boost build fails as well, I suspect it may, then you need to 
add it to your boost build command with

./b2 toolset=clang define=BOOST_NO_CXX11_ALLOCATOR ...

or maybe it is simpler to add something like

using clang : 3.4 :  : <cxxflags>-DBOOST_NO_CXX11_ALLOCATOR;

to your user-config.jam file, so you can just do the simpler

./b2 toolset=clang ...
