Installing Xcode 4.3 Confuses Homebrew (Briefly)

I have a lot of catching up to do, iOS-development-wise. Don't get me wrong, I absolutely love the work I get to do at my day job, which is All Clojure All The Time. But that doesn't leave a lot of time for iOS development.

I was able to convince graphviz to install without resorting to symlink-ing, using the following incantation:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/
