title: Getting Rails to play with Hpricot
body: <p>I'm trying to get Hpricot working with Rails on my dev machine.</p>
  
  <p>I've installed Hpricot [0.8.1] using the standard 'gem install hpricot' and confirmed it works fine with my standard Ruby installation [1.8.7]; however when I try the same with my Rails [2.1.0] installation, I get an error -</p>
  
  <p>TypeError: superclass mismatch for class BogusETag from /usr/lib/ruby/1.8/hpricot/tag.rb:130</p>
  
  <p>Seems like there's some kind of conflict, but googling the error hasn't turned up any useful information.</p>
  
  <p>Any ideas ? Thanks in advance.</p>
