gcc-4.2 is not available on Xcode 4.2 and later -- the same versions of Xcode which would default to clang -- so you cannot rely on it exclusively.

Also, what of llvm-gcc-4.2?

See:

https://trac.macports.org/wiki/PortfileRecipes#compiler

If llvm-gcc-4.2 works, use that (2nd block of code at that link). If only gcc-4.2 works, use that but fall back to apple-gcc42 (3rd block of code).
