This was incredibly helpful! I downgraded to 1.9.3-p392 and passenger installed just fine! Good show, sir!

The rails ready installer listed here is now installing ruby 2.0.0. Passenger doesn’t currently support 2.0.0 To fix this: rvm uninstall 2.0.0 rvm install 1.9.3-p392 gem install bundler passenger passenger-install-apache2-module
