Команды подавались подряд, текст скопирован из терминала.
Вентилятор крутится, чипы холодные. Сборка джона (magnum ripper 1.8.0.13)
прошла успешно. Opencl не устанавливал.
Запуск под sudo выводит те же результаты. Что можно сделать?   Подскажите,
пожалуйста!

Commands were submitted in a row, the text was copied from the terminal.
The fan is spinning, the chips are cold. JtR`s assembly (magnum ripper
1.8.0.13) was successful. Opencl did not installed.
