Система Debian. Ситуация следующая. Нужен был выб-интерфейс для Cyrus-imap.
В итоге поставил webmin и на него плагин для cyrus.
Плагин не работает, требует установки доп. модуля perl, пишет:

Error: some Perl modules are missing:
    * Tree::Simple

Стал разбираться как ставить...

После команды

Короче какие-то неудолетворенные зависимости, как не крути не ставиться.
из tar.gz тоже пробовал.

тоже не помогаем.
В общем я вообще никогда с perl не сталкивался, по докам не осилил, в гугле тоже не нашёл. Помогите плз.
