title: Difficulty with activesupport when attempting to deploy
body: <p>I have a rails application that I am trying to deploy onto the internet. I have setup a server on the Amazon EC2 cloud, that I know works because I have deployed another site to the same machine.</p>
  
  <p>When I try to run this new application either through 'rails console' or when running 'rake db:seed' or just by trying to browse to the application, rails crashes saying it cannot find activiesupport: </p>
  
  <blockquote>
    <p>/home/ec2-user/.gem/ruby/1.9.1/gems/activesupport-3.2.2/lib/active_support/core_ext/big_decimal/conversions.rb:1:in `require': cannot load such file -- bigdecimal (LoadError)</p>
  </blockquote>
  
  <p>My Rails version is 3.2.2 and I'm using ruby 1.9.3p0 (2011-10-30) [x86_64-linux]. My database is MongoDB which I access through Mongoid. And I'm using Passenger and Apache as a server.</p>
  
  <p>Is there any configuration step or something like that that I have missed?</p>
  
  <p>P.S. I know I shouldn't be using ec2-user, I'm still experimenting. And also, I've never had much luck with RVM.</p>
