Rails 3.1 engine rake db:test:prepare task missing

Question

I'm working on a rails 3.1 engine, and as it's a brand new release and I'm working off of edge, I didn't expect things to go perfectly. I can't seem to get my engine to see the db:test:prepare task when I run bundle exec rake -T

I'm using rake 0.8.7 and edge rails. If I try to require the dummy application's Rakefile, I get

undefined method 'prerequisites' for nil:NilClass on line 7 of spec/dummy/Rakefile

Line 7 of my Rakefile in spec/dummy/ is Dummy::Application.load_tasks

My research so far has brought me to http://www.engineyard.com/blog/2010/rails-3-beta-is-out-a-retrospective/ which corresponds with databases.rake in Active Record.

How do I get the db:test:prepare task into my engine?
