Installing passenger to work with apache for rails application is especially pleasant since it gives you direction to setup apache passenger module properly. I have done it several times and it has always worked. Recently I had to change the version of ruby that passenger uses and all I had to do is change the PassengerRuby directive in httpd.conf (or apache.conf) as follows:

#LoadModule passenger_module /opt/ruby-enterprise-1.8.6-20090421/lib/ruby/gems/1.8/gems/passenger-2.2.2/ext/apache2/mod_passenger.so
#PassengerRoot /opt/ruby-enterprise-1.8.6-20090421/lib/ruby/gems/1.8/gems/passenger-2.2.2
#PassengerRuby /opt/ruby-enterprise-1.8.6-20090421/bin/ruby
LoadModule passenger_module /opt/ruby/lib/ruby/gems/1.8/gems/passenger-2.1.2/ext/apache2/mod_passenger.so
PassengerRoot /opt/ruby/lib/ruby/gems/1.8/gems/passenger-2.1.2
PassengerRuby /opt/ruby/bin/ruby

I am not sure if this is the recommended way but it worked for me.

Enjoy!
