Проблемы с установкой RarCrack

Я довольно новичок в Linux. В настоящее время я работаю на Ubuntu 10.04 Desktop. Во всяком случае, некоторое время назад, будучи слегка пьяным, я зашифровал файл .rar с паролем и удалил оригинальные файлы. Теперь я действительно хочу вернуть эти файлы, поэтому я скачал последнюю версию rarcrack (0.2).

Я не могу установить его! Вот что происходит, когда я захожу в папку rarcarck-0.2 и набираю «make», как указано на их сайте.

root@linux:~/rarcrack-0.2# make
gcc -pthread rarcrack.c `xml2-config --libs --cflags` -O2 -o rarcrack

make: *** [all] Error 1

И вот что происходит, когда я набираю «make install».

root@linux:~/rarcrack-0.2# make install
install -s rarcrack /usr/bin/bin
install: cannot stat `rarcrack': No such file or directory
make: *** [install] Error 1

ЛЮБАЯ помощь будет ОЧЕНЬ признательна. Заранее спасибо!
