How to run ScrAPI with Ruby?

Question

I'm trying to run scrapi with rails with this code:

require 'rubygems'
require 'scrapi'
require 'tidy'

scraper = Scraper.define do
    process "title", :page_name => :text
    result :page_name
end

uri = URI.parse("http://railscasts.com/episodes/173-screen-scraping-with-scrapi")
p scraper.scrape(uri)

but I get the following error:

DL is deprecated, please use Fiddle
/usr/local/rvm/gems/ruby-2.0.0-p353/gems/tidy-1.1.2/lib/tidy/tidybuf.rb:5:in `<class:Tidybuf>': uninitialized constant DL::Importable (NameError)

        from scrapitest.rb:3:in `<main>'

has anybody got an idea why is that and what could I do to fix it?

Thank you.

Try http://github.com/libc/tidy_ffi instead. It seems tidy gem is not mantained anymore.
