 Uninstalled XCode 4.2, installed XCode 4.3. Now anything that depends on C
 compiler fails to build, because path to clang is used as
 $DEVELOPER/usr/bin/clang, which is wrong for 4.3. For example:

 {{{
 $ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
 $ sudo port -v install graphviz
 [...]
 checking for gcc...
 /Applications/Xcode.app/Contents/Developer/usr/bin/clang
 checking for C compiler default output file name...
 configure: error: C compiler cannot create executables
 See `config.log' for more details.
 [...]
 $ sudo port -v install mercurial
 [...]
 building 'mercurial.base85' extension
 /Applications/Xcode.app/Contents/Developer/usr/bin/clang [...]
 unable to execute
 /Applications/Xcode.app/Contents/Developer/usr/bin/clang: No such file or
 directory
 [...]
 $ xcrun -find clang
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
 }}}

 If I use xcode-select to switch to / then {{{xcodebuild -version}}} calls
 take forever because they scan my whole hard-drive, so currently there's
 no {{{xcode-select -switch}}} path that would work for all needed tools.

 Perhaps macports should use xcrun -find to find actual locations of
 executables.

 P.S. I know XCode 4.3 was just released, I'm logging it in case it's
 useful.
