clang++-mp-3.4 doesn't find initializer_list on OS X 10.6

[Jeremy Huddleston Sequoia]

Yes, if you want C++11 on Snow Leopard, you need to install the libcxx port and use clang-3.3 or later.

Also, I believe you may need to add -stdlib=libc++ in addition to -std=c++11.  I think it should be implied, but I forget if it is.
