NoMethodError

#simple ebay example

require 'rubygems'
require 'scrubyt'

ebay_data = Scrubyt::Extractor.define do

fetch 'http://www.ebay.com/'
fill_textfield 'satitle', 'ipod'
submit

record "//table[@class='nol']" do
name "//td[@class='details']/div/a"
end
end

puts ebay_data.to_xml

-------

when I run 'ruby ebay_3.rb' I get:

what should I do?
do I have to reinstall the gems scrubyt etc? does ruby need to be
reinstalled? Does this have something to do with windows? should I be
running this on a linux platform instead? (or maybe I should just get a
mac).
