Basic steps to get RVM, Ruby and Passenger running on a CentOS cPanel / WHM Server

This initial guide was pretty accurate and worked through most of the installation - up until running

# bundle exec rake assets:precompile

Attempting to precompile assets threw a rake error about a missing Javascript Runtime. So I went to install Nodejs only to realize it required Python 2.6 or greater. But CentOS 5.8 depends on Python 2.4. It's possible to have both versions installed and play nicely without breaking cPanel by using the 'alternatives' program (man alternatives).
