How do I access Kaminari's path_to_next_page method in controller?

Question

I need to access Kaminari's path_to_next_page method in my controller, how can this be done? I've tried this to include in controller include Kaminari::Helpers::UrlHelper works fine on development server, but on heroku it crashes the app... Any ideas?
