невстреченные зависимости при установке нс-allinone2.29.2 на Ubuntu 14.04?

Я устанавливаю ns2-allinone-2.29.2 (не последнее, мне было нужно это для тестирования Св.) на Ubuntu 14.04, и получил вышеупомянутую проблему. Даже при том, что зависимости установлены, это не может распознать его. Помогите! Я люблю Linux!!!
