Error using rails Mail_form gem: "uninitialized constant Mailform"

Question

So, I've checked all the existing answers to similar questions here on stackoverflow and elsewhere, but cannot get the mail_form gem to work as advertised.

Here's the setup: I'm trying to create a simple lead capture form for my company's website. I want to email the data collected by the form to my email account without a database backend and I thought that's what mail_form would make easy.

Here is my model, ContactForm.rb:

class ContactForm < Mailform::Base
  attribute :name,     :validate => true
  attribute :email,    :validate => /\A([\w\.%\+\-]+)@([\w]{2,})\z/i
  attribute :file,     :attachment => true
  attribute :phone 
  attribute :referral
  attribute :message
  attribute :nickname, :captcha => true

  def persisted?
    false
  end

  def headers
    {
      :subject => "New Lead",
      :to => "[email protected]",
      :from => %("#{name}" <#{email}>)
    }
  end
end

And here's my controller, contact_forms_controller.rb:

class ContactFormsController < ApplicationController
  def new
    @contact_form = ContactForm.new
  end

  def create
    begin
      @contact_form = ContactForm.new(params[:contact_form])
      @contact_form.request = request
      if @contact_form.deliver
        flash.now[:notice] = 'Thank you for your interest!'
        redirect_to root_path
      else
        render :new
      end
    rescue ScriptError
      flash[:error] = 'Sorry, something was wrong'
    end
  end
end

And here is my view, contact_forms/new.html.erb:

<%= form_for @contact_form do |f| %>
 <div class="field">
   <%= f.label :name %>
  <%= f.text_field :name, :required => true %>(required)<br /><br><br>
 </div>
 <div class="field">
  <%= f.label :email %>
  <%= f.email_field :email, :required => true %>(required)
  <br /><br><br>
 </div>
  <div class="field">
  <%= f.label :phone %>
  <%= f.phone_field :phone %><br /><br><br>
 </div>
  <div class="field">
  How did you hear about us?:<br /> <%= f.text_field :referral
  %><br /><br><br>
 </div> 
  <div class="field">
  Comments (What types of wine are you
  interested in?):<br / <%= f.text_area :message %><br /><br><br>
</div>
 <div class="field">
  Submit: <%= f.submit "Create" %>
</div>

<% end %>

I'm pretty new to rails and web programming in general, so it might well be that I am missing something REALLY basic here that isn't mentioned in any online tutorials. I've been all over the mail_form documentation and every tutorial and answer I can find and I'm still getting the error.

Oh yes! I also get the error if I try ContactForm.new in the rails console. Any help would be greatly appreciated!

Oh yes, Rails version 3.1.1

If you're trying this for the first time from console, be sure to restart your rails console after installing your gem.
