Below are the steps for a fresh installation if you need it at any time:

bash -sk stable < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

source ~/.bash_profile

source /etc/profile.d/rvm.sh

rvm requirements #Lets you know the system dependencies and if you need to install any other libraries

rvm install 1.9.2-p290

rvm use 1.9.2 --default

rvm gemset create demo

rvm demo@1.9.2

then install rails

gem install rails -v=3.0.4

If at any time u mess up your rvm you can remove it using rvm implode or rm -rf ~/.rvm
