Environment info:

Ruby 1.9.1-p376  
Rails 2.3.5  
Apache2 with Passenger mod

I installed the nokogiri gem like I would any other gem however when I  
require it at the top of my controller and access it through apache, I  
get an error saying “Missing source file” and it lists nokogiri. I  
have other gems required at the top and when I don’t have nokogiri  
required everything works fine.

Also when I try requiring nokogiri in the console I don’t get that  
error.

I was told that this is a Rails issue so any help would be appreciated.
