Use the blacklist versions port group and blacklist maybe {clang < 300}, {clang < 421}, or {clang < 425} depending on what works.  You should append 3.2 and 3.1 to fallbacks since 3.3 will be in the blacklist (I'm still curious why that is).

So now I have

To make this work though, I also need to black list any compiler that isn't clang, so on systems where the default system compiler isn't clang, it will fallback to the macports-clang, no ? whats the string to add to the blacklist list for this ?
