how can I send an email from an IronWorker for a rails3 app?

Question

I followed all the docs for IronWorkerNG::Client.new and rails:

https://github.com/iron-io/iron_worker_rails_example

My .worker file is doing:

runtime 'ruby'

name 'CompanyList'

merge_gem 'activerecord'
merge_gem 'actionmailer'
merge_gem 'pg'
merge_gem 'aws-s3'

dir '../app/models'
file '../app/mailers/result_mailer.rb'
file "../app/views/result_mailer/email.html.erb", "result_mailer"

exec 'company_list.rb'
remote

and my ruby file does:

require 'action_mailer'
require 'active_record'
require 'aws/s3'
require 'pg'
require 'models/company_list.rb' 
require 'result_mailer.rb'

puts "Starting CompanyList worker at #{Time.now}"

ActiveRecord::Base.establish_connection(params['database'])
mailer_config = params['mailer'].inject({}) { |memo, (k, v)| memo[k.to_sym] = v; memo }
#ActionMailer::Base.prepend_view_path('.')
ActionMailer::Base.view_paths = ['.']
ActionMailer::Base.smtp_settings = mailer_config
ActionMailer::Base.delivery_method = :smtp

But everytime I get this error:

/task/__gems__/gems/actionmailer-2.3.18/lib/action_mailer/base.rb:433:
in `method_missing': undefined method `email' for ResultMailer:Class 
(NoMethodError)
from /task/models/company_list.rb:16:in `process_file'
from /task/company_list.rb:18:in `<top (required)>'
from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from __runner__.rb:213:in `<main>'

and ResultMailer DOES have an email method:

class ResultMailer < ActionMailer::Base

  def email
    to = 'andrew@testdomain.com'
    mail :from => 'test@testdomain.com', :to => to, :subject => "Test"
  end

end

any idea why action_mailer base line 433 is throwing that error? I can call ResultMailer.email.deliver from the console on my local system just fine. This error is on production with heroku and iron.io.

ah, sometimes writing out the question on stackoverflow makes you see the problem. I needed:

merge_gem "activerecord", "=3.2.8"
merge_gem 'actionmailer', '=3.2.8'

without the 3.2.8 version it was using an old old version of action mailer.
