Is anyone using Cinderella on their mac? #dev
"Cinderella is a fully managed development environment for open source hacking on Mac OSX. It's powered by rvm, homebrew and chef. You only need Xcode to get started.

Cinderella builds everything up in ~/Developer. It won't stomp on any of your current installations so you don't have to commit your entire machine immediately. It's simple to rollback if you really want to."
