libcppa on Mountain Lion

I have just upgraded my Mac and I have good news for all Apple users out there!

If you have switched to Mountain Lion or have plans to do so, you will find clang++ in version 4.0 after installing XCode. Hence, there is finally no need to get a recent compiler from an external source. libcppa 0.3 compiles and runs like a charm after installing CMake and Boost from MacPorts.
