An error occured while installing nokogiri (1.5.0), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.0'` succeeds before bundling.

You can skip this part. The error message is pretty much self explanatory, but the website requires a few more words explaining the code.

Any thoughts?

You need to have all the necessary libraries installed on your machine. When you installed RVM , it should have listed this for you. On the current version of rvm, you can run rvm requirements to see the exact list. Right now, that list is:

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
