Casein notifications

Does anyone have any experience with upgrading the Casein gem when they upgrade to Rails3?

When I upgraded my app to Rails 3 I came across an issue with the Casein 3.1.0 gem.

It is breaking my cucumber tests with the following error:

undefined local variable or method `casein_config_email_from_address' for Casein::CaseinNotification:Class (NameError)

But the method IS defined in the Casein::ConfigHelper:

module Casein::ConfigHelper

  # Text string containing the name of the website or client
  # Used in text and titles throughout Casein
  def casein_config_website_name
    'Casein'
  end

  # URL to the logo used for the login screen and top banner - it should be a transparent PNG
  def casein_config_logo
    '/casein/images/casein.png'
  end

  # The server hostname where Casein will run
  def casein_config_hostname
    if ENV['RAILS_ENV'] == 'production'
      'http://ift.tt/1DyltTL'
    else
      'http://localhost:3000'
    end
  end

  # The sender email address used for notifications
  def casein_config_email_from_address
    'donotreply@caseincms.com'
  end

  # The page that the user is shown when they login or click the logo
  # do not point this at casein/index!
  def casein_config_dashboard_url
    url_for :controller => :casein, :action => :blank
  end

  # A list of stylesheet files to include in the page head section
  def casein_config_stylesheet_includes
    ['/casein/stylesheets/custom.css', '/casein/stylesheets/screen.css', '/casein/stylesheets/elements.css']
  end

  # A list of JavaScript files to include in the page head section
  def casein_config_javascript_includes
    ['/casein/javascripts/custom.js', '/casein/javascripts/casein.js', '/javascripts/prototype.js']
  end

end

and when I look at the file it mentions (/Users/camillavk/.rvm/gems/ruby-1.9.3-p551@rails3/gems/casein-3.1.0/app/mailers/casein/casein_notification.rb:8:in `') it has this:

module Casein

  require 'casein/config_helper'
    include Casein::ConfigHelper

  class CaseinNotification < ActionMailer::Base

    default :from => casein_config_email_from_address

    self.prepend_view_path File.join(File.dirname(__FILE__), '..', 'views', 'casein')
....
end

I don't know why it's not seeing the method and don't know if I'm meant to change the default :from => casein_config_email_from_address or not?
