Попытка установить ncview на Ubuntu 12.04 [дубликат]

Для пакета ncview требуются заголовки и заголовки разработки X .

В Ubuntu 12.04 я попробовал следующую команду sudo apt-get install xorg-dev и получил следующее сообщение об ошибке.

Это выглядит как очень длинный список пакетов. Что-то мне не хватает?
