I figured out a way to very quickly and painlessly install Ruby on
Rails with all the up-to-date gems, etc. I put it up on GitHub.
With that the install takes 5 minutes and you'll have a full RoR
system up and running with minimal further configuration. It has Ruby
1.9.2, Rails 3.1, MySQL 5.5 and PHPMyAdmin & all gems installed to
create and run Rails projects. I was even able to get mysql2 working
I'd like to get this news to as many people as possible because it
sure would have saved me hours if I used this one.
