Comment (by ryandesign@…):

 I'm confused. Apple stated in the Xcode release notes that "Xcode 4.6 is
 the last release to include the LLVM-GCC compiler". Then why does /usr/bin
 /llvm-gcc-4.2 exist in Xcode 5? Is it a symlink to clang or something?
 Because that looks like the kind of output clang would produce, not the
 kind of output llvm-gcc-4.2 would produce.

 I think what I'd like to do is improve the compiler_blacklist_versions
 portgroup so that if it cannot find the version number string, then it
 considers the compiler blacklisted instead of throwing an error.
