RailsInstaller for OS X Released

Just last week I decided that it could not wait, I had written an article on installing Ruby on Rails on OS X.  While not very difficult, there are a few steps involved, and it's not something that's completely obvious how to do for the newcomer.  No sooner than I had written this article, the awesome guys at EngineYard released RailsInstaller for OS X.  I have yet to test it, but assuming it all works according to plan, it should be the simplest and only recommended way to install Rails for both the professional and newbie.
