How do I get the command line builds tools installed with current Xcode / Mac OS X v10.8 (Mountain Lion) or later?
Unlike Xcode there is no installer (it's just a bundle).
It looks like all the command line tools are there (in the bundle, under Contents/Developer), but none of the appropriate environment variables set to use them.
Is there a script somewhere I can run that will setup my environment to support building from the command line?
