Rails: undefined method 'paginates_per' - ruby-on-rails

Question

I'm installing a gem called Carrier https://github.com/stanislaw/carrier/blob/master/Gemfile into a Rails 3.2.1 app. It uses Kaminari and when I did bundle install after adding gem "carrier" to my Gemfile, it showed that I was using kaminari
Using kaminari (0.13.0)
However, when I tried to rake db:migrate, I got this error
rake aborted
undefined method `paginates_per' for Carrier::Chain(Table doesn't exist):Class
Can anyone suggest a fix for this? I've copied the gemfile from the Carrier gem below and the Gemfile for my own app below that
(Carrier gem Gemfile)
source "http://rubygems.org"
gem 'require_all'
gem 'kaminari'
gem 'unread'
gem 'sugar-high'
gem 'sweetloader'
group :development, :test do
gem 'rails', '~> 3.1.0'
gem 'unicorn'
gem 'mysql2'
gem 'devise'
gem 'rake-kit'
gem 'cutter'
gem "jeweler", ">= 1.6.4"
gem "rspec-rails", '>= 2.5'
end
group :test do
gem 'capybara'
gem 'factory_girl'
gem 'spork'
gem "launchy"
gem 'shoulda'
end
Gemfile for my starter app
source 'https://rubygems.org'
gem 'rails', '3.2.1'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'pg'
gem 'devise'
gem 'carrier'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
Update These are the migrations it installed when I ran install:migrations
rake carrier:install:migrations
Copied migration 20120229055640_create_messages.carrier.rb from carrier
Copied migration 20120229055641_create_chains.carrier.rb from carrier
Update
I tried to reinstall it again on another git branch it this time I got a slightly different error when I ran rake db:migrate
rake aborted!
undefined method `acts_as_readable' for Carrier::Message(Table doesn't exist):Class
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)

You appear to be missing some database backing for what Carrier is trying to do. From the Carrier readme, it looks like you need to run rake carrier:install:migrations before running db:migrate. Have you done that?
