    To activate Phusion Passenger for Apache, create /etc/apache2/other/passenger.conf:
      LoadModule passenger_module #{opt_prefix}/libexec/buildout/apache2/mod_passenger.so
      PassengerRoot #{opt_prefix}
      PassengerDefaultRuby /usr/bin/ruby

    To activate Phusion Passenger for Nginx, run:
      brew install nginx --with-passenger
    EOS
