Sounds like the qt portgroup says "clang" is the only acceptable compiler, and the cxx11 portgroup says "clang" < 500 is not acceptable. Since the last version of "clang" on Lion was 425, it gets blacklisted, leaving no acceptable compilers.

I would guess there is no reason, other than stubbornness, for the qt build to require specifically /usr/bin/clang, as opposed to a compatible version of clang installed by MacPorts.

I am working on it.
