 Leopard and Snow Leopard do not have libc++ installed by the OS, but MacPorts can build and install system roots that contain these runtimes for your use.  After installing these roots (which is done automatically when the libcxxabi and libcxx ports activate), you can choose to continue using libstdc++ as the default C++ runtime in MacPorts or configure MacPorts to use the new libc++ runtime.

 1. Start with a new install of MacPorts or '''uninstall all ports that use C++'''
 2. Install the libcxx port.  When it activates, the libcxxabi and libcxx ports will install libc++.dylib and libc++abi.dylib (which will remain after you uninstall MacPorts).  This will pull in a number of dependencies.

+At this point, you will have libc++ installed and can use clang++-mp-3.4 -stdlib=libc++ for your personal projects, but like Lion and Mountain Lion, MacPorts will continue to use libstdc++ by default unless you continue with the next step.
