Install Ruby using RVM

The easiest way to install RVM, which is also the eaisest way to install [Ruby on Rails](Ruby on Rails) and JRuby, a Ruby implementation built ontop of the Java Virtual Machine.

WARNING! If you are running tmux inside the terminal you are using, exit that first! Some of the RVM installation stuff might not install right within it.

For this installation, we're going to go all out and install Ruby on Rails with Ruby.

cd ~
gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3  # Note: If this fails, try running it again.
curl -SL https://get.rvm.io | bash -s stable --rails       # Install Ruby. Adding --rails also installs RoR
source ~/.rvm/scripts/rvm                                  # Activate RVM
rvm requirements                                           # See any dependency requirements
echo `export PATH="$PATH:$HOME/.rvm/bin"' >> ~/.profile    # Add the RVM path to $PATH

NOTE: RVM will look for these packages in apt-get: gawk, libreadline6-dev, libssl-dev, libyaml-dev, libsqlite3-dev, sqlite3, libgdbm-dev, libncurses5-dev, bison, libffi-dev.
