If you're following this guide on MongoDB with Ruby on Rails, and you get an error message There was an error in your Gemfile, and Bundler cannot continue after entering bundle install, you can follow the steps specified in this post to complete the "Bundling" stage.
I am assuming that you've tried the recommended work around and yet still getting the error message above.
First, install bson_ext.
gem install bson_ext
Output:

Instead of requiring or loading 'rubygems', we'll just make sure that both mongo and bson_ext are in our load path when we require mongo
To load both mongo and bson_ext in your path, edit the application.rb file.
