hi there, I dont know if you want an answer or you just left this here for no reason, but today I was doing the #385 railscast and found this there

I dont seem to find answer for this in actual build of rspec and all that, but I did solve it with changing my Gemfile

on the bottom

gem "rspec-rails", :group => [:test, :development]
group :test do
gem "factory_girl_rails"
gem "capybara"
gem "guard-rspec", '> 2.0.0'
gem 'rspec', '> 2.11.0'
end

and then delete lock file and bundle and you are ok again :)

(and I think you already noticed, but ryan uses build it has to be FactoryGirl.build)

I hope this helps :)
have a nice day :)
