You can only pass a proc to #World once, but it's happening
in 2 places:

Ruby/Gems/1.8/gems/cucumber-0.6.2/examples/ramaze/features/support/env.rb:32:in `World'
Ruby/Gems/1.8/gems/cucumber-0.6.2/examples/selenium_webrat/features/support/env.rb:25:in `World'

Use Ruby modules instead to extend your worlds. See the Cucumber::RbSupport::RbDsl#World RDoc
or http://wiki.github.com/aslakhellesoy/cucumber/a-whole-new-world.
