 compiler will never be llvm-gcc-4.2 on Xcode 4.2 and up. On the mailing
 list I [http://lists.macosforge.org/pipermail/macports-
 dev/2012-May/019305.html already provided] the simpler block that should
 be used, provided it is actually verified by someone with Xcode 4.1 that
 that was really the problem.

 Compiling with clang on 4.2 is fine (and I have tested). gcc-4.2 isn't
 installed with Xcode 4.3 (only left over from a previous 4.2 installation)
 so one of the llvm compilers need to be used. In fact, both llvm-gcc-4.2
 and clang work for Xcode >= 4.3
