I’m using RVM to handle basicly two Rubies, REE and 1.9.1. I want to  
make sure that my Rails app works with both. For some reason it seems  
that Passenger can’t find my 1.9.1 Rails gem located in  
/home/myhome/.rvm/gems/ruby-1.9.1-p378/gems/rails-2.3.5. REE version of  
Rails gem is located in  
/home/myhome/.rvm/gems/ree-1.8.7-2010.01/gems/rails-2.3.5.

“Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`,  
update your RAILS\_GEM\_VERSION setting in config/environment.rb for the  
Rails version you do have installed, or comment out RAILS\_GEM\_VERSION to  
use the latest version installed.”

I have following lines in Apache conf files:  
/etc/apache2/mods-enabled/passenger.load: “LoadModule passenger\_module  
/home/pkivikan/.rvm/gems/ruby-1.9.1-p378/gems/passenger-2.2.11/ext/apache2/mod\_passenger.so”

/etc/apache2/mods-enabled/passenger.conf: “PassengerRoot  
/home/pkivikan/.rvm/gems/ruby-1.9.1-p378/gems/passenger-2.2.11”  
“PassengerRuby /home/pkivikan/.rvm/rubies/ruby-1.9.1-p378/bin/ruby”

script/server (webrick) also loads Rails properly with 1.9.1, so why  
isn’t Passenger loading Rails when using Ruby 1.9.1?
