Removed rbenv, installed Passenger

rbenv was causing issues, primarily because vagrant operates in two different ways during vagrant ssh and vagrant provision.

Could spend time trying to fix that… but reality is that this build only needs one version of ruby on it. So, building from source, and this becomes the default system ruby.

That allowed passenger and apache install to finish.

Going to test my app now on this server.
