Warning: All compilers are either blacklisted or unavailable

Hi,

When upgrading Qt5 I'm greeted with:

--->  qt5-mac is replaced by qt5
Warning: All compilers are either blacklisted or unavailable;
defaulting to first fallback option

I guess this is because of the cxx11 PortGroup, even though I'm not 100% sure.

But the main question is: why are all compilers blacklisted or rather:
can something be done to have some compiler in the fallback that would
work (like mp-clang-3.4)? Lion's clang (425) usually works, even
though there are some problems with it (not all C++11 code works).
