bip_select + Capybara = Capybara::NotSupportedByDriverError ?

I'm having trouble with bip_select on Capybara.

it "[update] should process the best_in_place form submission", :js do
  visit financials_fringe_descriptions_path
  bip_select fringe_description, :fringe_rate_name, fringe.to_s
  ...
end

Firefox visits the page, but as soon as bip_select executes I get this:

     Failure/Error: bip_select fringe_description, :fringe_rate_name, fringe.to_s

     Capybara::NotSupportedByDriverError:

I think it's worth noting bip_text works with my setup fine.
