Just a note about GCC/XCode on Lion (esp. if using homebrew): The default GCC installed by Xcode is no longer GCC you expect it too be, it's actually a hybrid of LLVM and GCC /usr/bin/gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 A non-hybrid version in installed at: /usr/bin/gcc-4.2 --version i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 It's a rather important change to GCC on mac, it even broke `brew install mysql` for awhile: https://github.com/mxcl/homebrew/issues/6277 https://github.com/mxcl/homebrew/issues/6277 Some great hackers found out it was linking to Apple's internal pthread library. Code-softly hackers.
