On rails 3.2.3 and steak 2.0.0, I couldn't run
Here is the output
Don't know how to build task 'spec:acceptance'
(See full trace by running task with --trace)
Is this specific of Rails 3.2.3? Have you try with other versions?
I just try with Rails 3.2.1 and this problem does not occur.
Same problem here with rails 3.0.9 and steak 2.0.0.
The issue seems to be resolved by requiring capybara/rspec in spec/rails_helper.rb.
