Yes its 2011 and Rails 3 has been out for a year but as far as I can tell, and many git reset --hard HEAD attempts later, haml requires the gem haml-rails to generate views. Even though Google may show results from 2010 they are still relevant. But haml --rails isn't what you want.

So Haml configuration in my Rails 3.0.9 project looks like (only relevant parts shown)...

#Gemfile  
⋮
gem 'haml'  
group :development do  
  gem 'haml-rails'
  ⋮
end
#./config/application.rb  
⋮
module IlkContent  
  class Application < Rails::Application
  ⋮
  config.generators do |g|
    g.template_engine :haml
    ⋮
  end
end  
⋮
