неопределенный метод «встроенный» для ImageScience: Class (NoMethodError)

Я переношу приложение Rails 2.1.2 на Rails 2.3.11.

Чтобы упростить себе жизнь, я использовал упаковщик, но при запуске сервера получаю следующую ошибку:

/Library/Ruby/Gems/1.8/gems/image_science-1.2.1/lib/image_science.rb:90: undefined method `inline' for ImageScience:Class (NoMethodError)

Это немного странно, потому что я заработал без упаковщика. Я думаю, что мне не хватает зависимости от драгоценного камня.
