OUTPUT FROM ATTEMPTING APACHE RESTART (sudo /etc/init.d/apache2 restart)

 * Restarting web server apache2
apache2: Syntax error on line 320 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/extras/passenger.conf: Cannot load /usr/local/ruby-enterprise/lib/ruby/gems/1.8/gems/passenger-2.2.4/ext/apache2/mod_passenger.so into server: /usr/local/ruby-enterprise/lib/ruby/gems/1.8/gems/passenger-2.2.4/ext/apache2/mod_passenger.so: cannot open shared object file: No such file or directory
   ...fail!


QUESTION

Why has mod_passenger.so not been created by running the passenger-stack sprinkle scripts?
