Thanks for the information. I am not an expert on clang, but here is my experience: I had Xcode 4 and command line tools add-ons installed. I upgraded to Xcode 5 and then I (as usual) went into Xcode Preferences -> Downloads and chose to install "command line tools".
I now have the same version of clang as Prof. Ripley describes above, and I also get sleipner:~ $ gcc --version Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 5.0 (clang-500.2.76) (based on LLVM 3.3svn) Target: x86_64-apple-darwin12.5.0 Thread model: posix I did not need to download anything from the developer website. Question: I am still using the build of GCC 4.2 which Simon supplies sleipner:~ $ /usr/bin/gcc-4.2 --version i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3) Copyright (C) 2007 Free Software Foundation, Inc.

I see in R-admin that CRAN is now built using llvm-gcc-4.2. I assume this is now the recommended tool and I should switch?
