This sounds like it may be a config issue then - 
BOOST_NO_CXX11_ALLOCATOR should be set for GCC-4.6.x and earlier. 
However it's next to impossible to correctly identify the libstdc++ 
version when using clang (there's a long discussion about this here 
https://svn.boost.org/trac/boost/ticket/7473).

So:

1) Is Boost.Config setting BOOST_NO_CXX11_ALLOCATOR for clang on top of 
gcc-4.6.x std lib?
2) If not, what value is BOOST_LIBSTDCXX_VERSION set to?

Thanks, John.
