No definition for owned_eh

Unfortunately, it doesn't work at all. And even more unfortunately, it's not
easy for me to debug, because while 'pp page.parser' in the Hpricot case
gives a detailed result from the parsing process, it just gives:
#<Nokogiri::HTML::Document:0x7f06c01d3260
 @decorators={"node"=>[], "nodeset"=>[]}>
in the nokogiri version.

I have distilled a small example, without too many dependencies:
#!/usr/bin/ruby -w

require 'rubygems'
if ENV['NOKOGIRI']
  require 'nokogiri'
end
require 'mechanize'

if ENV['NOKOGIRI']
  WWW::Mechanize.html_parser = Nokogiri::HTML
end

class ImdbScraper
  def initialize
    @agent = WWW::Mechanize.new { |agent|
      agent.user_agent_alias = 'Linux Mozilla'
    }
    @baseurl = 'http://www.imdb.com'
    page = @agent.get(@baseurl)
    @search = page.form('find')
  end
  def search(lookfor, year = nil)
    @search.q = lookfor
    page = @agent.submit(@search)
  end
end
s = ImdbScraper.new
page = s.search('The Catered Affair', '1956')
puts page.at('//div.info')

# end-of-program

Run with and without the NOKOGIRI environment variable set, and see the
difference.
Maybe I'm missing something else that is silently ignored ?

Cheers,

Han Holl
