Cant direct require a specific module for Capybara (require 'capybara/helpers'). its work for
require 'capybara/dsl'
or

(...)/ruby-1.9.2-p320/gems/activesupport-3.2.5/lib/active_support/dependencies.rb:251:in `require': no such file to load -- capybara/helpers.rb (LoadError)
I dont know why some modules alowed to load on require capybara/? and others not.
capybara/helpers is not available in the current stable version (1.1.3) of Capybara. It was added 3 months ago but is only available in 2.0.0.beta4.
