Have Xcode.4.2 users (last paid SL release) prefer llvm-gcc-4.2 for consistency across SL releases.  The version of clang in Xcode 4.2 is too old at this point and Xcode 4.2 is too infrequently used for us to guarantee reliability.  llvm-gcc is much more likely to be reliable due to its wider use on that platform with Xcode 3.2.6
