Just some notes i might update while going through the procedure.

To start with, gem might complain that bundler requires a higher version. Something like this might happen, when you run "sudo gem install rails": ERROR:  Error installing bundler: bundler requires RubyGems version >= 1.3.6 ERROR:  Error installing bundler:        bundler requires RubyGems version >= 1.3.6 If you run into that, you need to ask gem to update itself: sudo gem update --system Then rails' installation should work. Actually i get errors installing the documentation for some gems. Should look into that...
