How did you create this configuration? If you use cap install this usually doesn't happen. – will_in_wi

Your deploy.rb shouldn't have the require or load lines. Back up your configuration, delete your Capfile, config/deploy.rb, and config/deploy/*, then run cap install. Modify the generated config files to taste.

Make sure you have Capfile directly under the project directory. If Capfile contains a line like require 'bundler/capistrano'

Remove it, it should just work.

Add the following to your Capfile and not config/deploy.rb:

require 'bundler/capistrano'
