Требуется установка / установка плагина a52

Я пытаюсь скомпилировать и установить плагин a52, следуя инструкциям отсюда:

https://help.ubuntu.com/community/DigitalAC-3Pulseaudio

Это работало на Ubuntu 11.10, но дает мне некоторые ошибки, когда я пытаюсь скомпилировать плагин на Ubuntu 12.04. Я искал решение, но я не мог найти много на эту тему в целом, чтобы не говорить о решении. Я бы очень признателен за помощь в этом:
