John, Just to confirm, did this build work for you on Lion 10.7.2, with Xcode 4.3, and gcc version 4.2.1 (LLVM build 2336.9.00)? From you follow-up messages I am assuming that beta4-gcc still builds a copy of gcc-4.6 on top of everything else, correct?
I never was able to get clang to build sage on my Apple (10.7.2 with Xcode 4.2). I was wondering if a few of you who were able to successfully build sage on your Mac could chime in with your "uname - a" as well as Xcode and gcc versions. I'm on $ uname -a Darwin hyperion 11.3.0 Darwin Kernel Version 11.3.0: Thu Jan 12 18:47:41 PST 2012; root:xnu-1699.24.23~1/RELEASE_X86_64 x86_64 with $ gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00) and Xcode version 4.1.
