Hi
HAd a quick look and seems all pretty standard. Only one thing that is deprecated is in the the installation of autodl-irssi,
autodl2.cfg is no longer referenced. It's simply autodl.cfg now.
In some cases as well you may need to install irssi as well so on ubuntu/debian its depending if you are in root or not, (
use sudo if not root) apt-get install irssi
