IIRC libc++ on 10.7 is pretty limited in its c++11 support.  If you really want to use c++11 you'll probably have to increase your deployment target.  These days, I can't build several c++11 projects like clang itself and cppcheck on my 10.8 buildbot because it's c++11 support is too limited.

Cheers,
