I installed memcache on my windows machine ('cached\_model') and am now getting the following error when I run any of my unit tests:

undefined method `use\_transactional\_fixtures=' for Test::Unit::TestCase:Class (NoMethodError)

The root cause of the pproblem seems to originate from this inside my environment.rb file. require 'cached\_model'. If I remove this line, all is good. Of course I don't want to do this...

Everything I did originated from this article: [http://nubyonrails.com/articles/2006/08/17/memcached-basics-for-rails](http://nubyonrails.com/articles/2006/08/17/memcached-basics-for-rails)

Any ideas?

thanks, phil
