Rails - Jun 2006 - superclass mismatch for class Tag (TypeError)

I am trying to write a ruby script which includes both the
''RubyfulSoup''
gem for HTML scouring, and the rails environment so I can access the
database easily.  I get the following error when trying to run this
script.

/usr/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_view/helpers/../../action_controller/vendor/html-scanner/html/node.rb:276:
superclass mismatch for class Tag (TypeError)
        from

        from

        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require''
        from conflict.rb:3

I''ve distilled the offending code down to 3 lines; here are the
contents
of my scripts/spider/conflict.rb:

require ''rubyful_soup''
RAILS_ENV = ''development''
require File.dirname(__FILE__) + ''/../../config/environment''

It appears there are two Tag classes.  How do I resolve this conflict?

Cheers,
-Jason
