I think running xcode-select --install will fix your problem. If not, please do a search on the issues list for your error message. The one you have posted here is quite common and could be solved by browsing the wiki or the previously closed issues.

@joshfriend : Maybe it would be cool to detect if command-line tools are properly installed?

something like xcode-select -p can help, and xcode-select --install can be emitted automatically if necessary.
