Problems with capybara and cucumber

Hi folks,

i'm starting with BDD and i'm using rails3, spec, capybara and cucumber... but the problem is.. after downloading all the gems and running: script/rails generate rspec:install and the cucumber:install --rspec --capybara
there is a features directory but for example the paths.rb is missing... also the default step definitions are missing... and also there is no generator for generating features....

so i search google but i don't find how to make capybara's default step definitions work... for example i found on the internet that there should be for example such a step definitions

Given /^(?:|I )am on (.+)$/ do |page_name|
  visit path_to(page_name)
end

and basically there should be a paths.rb with stuff in it where i should add something like

when /task index page/
  tasks_path()

but as i told you there is no paths.rb... so i created it myself and put

def path_to(page_name)
  case page_name
    when /task index page/
      tasks_path()
  end
end

into it... but still the step is shown as undefined.. that means that there are no predefined step definitions (loaded)?

so am i missing an important point or what is up?

could please someone enlighten me :-)

Thank and regards
