Undefined symbols for architecture i386

I am trying to use motion-ocr with the following code:

Rakefile

``` ruby
$:.unshift("/Library/RubyMotion/lib")
require 'motion/project/template/ios'
require 'motion-ocr'

begin
  require 'bundler'
  Bundler.require
rescue LoadError
end

Motion::Project::App.setup do |app|
  # Use `rake config' to see complete project settings.
  app.name = 'ocr'
end
```

app_delegate.rb

``` ruby
class AppDelegate
  def application(application, didFinishLaunchingWithOptions: launchOptions)
    true
  end
end
```

Gemfile

``` ruby
source 'https://rubygems.org'

gem 'rake'
gem 'motion-ocr'
```

Running rake gets this error:

``` ruby
andy@cowboy[~/workspace/ocr]$ rake
There was an error in your Gemfile, and Bundler cannot continue.
