That sounds like you may not have included the compiler_blacklist_versions 1.0
portgroup. If you do that, it should do what you say: blacklist all MacPorts
clangs, and Xcode clangs less than 500. So on Macs with Xcode 4 or earlier,
you'll be building with llvm-gcc-4.2 or gcc-4.2. Is that really what you want?
If Xcode 5's clang is ok, presumably MacPorts clang 3.5 would work too, maybe
even 3.4, and those would probably be preferable to the old llvm-gcc or gcc.
