Hi,
Impossible to run minetest with IRC mod.
I made all the requirements, installed lua packages, however I got this :

ModError: Failed to load and run script from /home/amelaye/.minetest/mods/irc/init.lua:

You need to clone it with: git clone --recursive https://github.com/minetest-mods/irc.git so you get all submodules
