LinRails — Ruby On Rails For Linux
foobarf00 writes "LinRails is a binary package that includes Ruby-1.8.6, Rubygems-0.9.4, Rails 1.2.3, Mongrel 1.0.1, MySQL-5.0.41, ncurses-5.6, OpenSSL-0.9.8e, and zlib-1.2.3. Its goal is to make it easy to get a Ruby on Rails development environment running in no time. This initial 0.1 release doesn't have a Web server in the package; opinions are solicited as to which to include."
sudo aptitude install rails
Any questions?
Oh, and regarding foobarf00's reply: All the distributions strive to do exactly the same. Why would you want to keep track of versioning at two different upstream repositories (or... Do you use Gems? Well, s/two/many/ if you please) when you can keep all of your system's versions synchronized with The One True Source?
