On FreeBSD 9.x, C++11 is not supported out of the box. As I mentioned
in another thread, currently the only easy way is to build and install
world with the following in /etc/src.conf:
WITH_CLANG_IS_CC=y
WITH_LIBCPLUSPLUS=y
This will make clang the default compiler, and install libc++ headers
and libraries on the system.
Afterwards, you can use -stdlib=libc++ -std=c++11 in the CXXFLAGS for
your project.
