I have been having a problem with using Bundler and being able to access my gems without having to require them somewhere, as config.gem used to do that for me (as far as I know). In my Rails 3 app, I defined my Gemfile like so:
clear_sources
source "http://gemcutter.org"
source "http://gems.github.com"
bundle_path "vendor/bundler_gems"
## Bundle edge rails:
git "git://github.com/rails/arel.git"
git "git://github.com/rails/rack.git"
gem "rails", :git => "git://github.com/rails/rails.git"
## Bundle
gem "mongo_mapper", :git => "git://github.com/jnunemaker/mongomapper.git"
gem "bluecloth", ">= 2.0.0"
Then I run gem bundle, it bundles it all up like expected. Inside the environment.rb file that is included within boot.rb it looks like this:
# DO NOT MODIFY THIS FILE
module Bundler
file = File.expand_path(__FILE__)
dir = File.dirname(file)
ENV["PATH"] = "#{dir}/../../../../bin:#{ENV["PATH"]}"
ENV["RUBYOPT"] = "-r#{file} #{ENV["RUBYOPT"]}"

But when I try to access any of my gems, e.g. MongoMapper, Paperclip, Haml, etc. I get:
NameError: uninitialized constant MongoMapper
The same goes for any other gem. Does Bundler not include gems like the old Rails 2.0 did? Or is something messed up with my system?
Any help would be appreciated, thank you!
