Hi,
next follows a compile error with clang 3.1 c++11 just including

This is probably another manifestation of the issue with clang supporting the c++11 core language, but the libstdc++ not supporting it, namely, <ctsddef> not defining nullptr_t. I'm not sure how to fix that. !defined(BOOST_NO_CXX11_NULLPTR) does, in my opinion, imply that std::nullptr_t is present (along with nullptr itself). It's not clear how a library could offer nullptr support without using nullptr_t.
