BitNami RubyStack with support for Windows, Linux and OS X

We just released BitNami RubyStack. It is a free, all-in-one installer that provides a fast, easy way to develop and deploy Ruby on Rails applications. It includes Ruby, Subversion, MySQL, SQLite, ImageMagick, and several Ruby Gems, and will optionally install Apache 2.2 with rewrite and proxy support. It supports Windows, Linux, and OS X, so you can share the same Rails environment on multiple platforms. You can get more details and download the stack here:
