description             libc++ is a new implementation of the C++ standard library with support for C++11 and portions of C++14.

long_description        ${description} \

                        Because objects cannot be passed between different versions of the C++ runtime, this port must \

                        replace the host version in order to be used.  On Snow Leopard and earlier, this is done \

                        automatically because there is no existing host version of this library.  On Lion and later, \

                        users must build the port with +replacemnt_libcxx and install the root manually if they wish \

                        to replace the existing host implementation.
