There's many different ways to install Rails and those will always be available whether someone creates an installer or not as long as source code is available. However, there is a combination of Ruby, Rails, and the database choices that serve as its backend which are common for the "Make a new Rails app and ship to Heroku" workflow that should be easier for being so popular.

I'm really surprised Rails isn't just another component in the Heroku toolbelt. The default Ruby version in OS X is always outdated, the database preferred by Heroku (postgres) is also outdated in OS X, and getting the latest XCode or re-installing it to install brew to install postgres and changing the order of execution in the PATH to make sure it picks up the right version is a prescription for despair and angst. RVM only solves the Ruby and gem versioning problem.
