It's a bit late and I might be wrong, but a gem doesn't auto require other gems. So to fix it, you need to require 'gon' in your gem (probably in your lib/your_gem_name.rb file). A good example is Devise: https://github.com/plataformatec/devise/blob/master/lib/devise.rb. They do also a lot of stuff in between, but you can see the that ir requires the ORM, and Warden and other dependencies.
