You can also install the Xcode 4 command line tools and run "sudo xcode-select --switch /Applications/Xcode4.app" then you shouldn't need the --with-tools-dir configure argument (I have both 4.6 and 5 installed). The Xcode 5 command line tools clobber the gcc symlinks, which is (IMHO) a bug in Apples CL tools installer...


I think ultimately we should investigate using xcrun to find the tools rather than relying on xcode-select. With that we could build without having the command line tools installed at all. The configure script should be able to do this, then use the same mechanism as --with-tools-dir to set the tool path.

For example:
$ xcrun -f clang
/Applications/Xcode_4.6.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
