This game supports VI keys and xkbcomp works, so no need to hard remap/recompile. You can create your own mapping for it (step by step instructions in wiki) and then use this script to fire it up:

#!/bin/sh
cd /opt/brogue
xkbcomp server-0.xkb :0
./brogue
setxkbmap

It will also reset you keyboard back to default layout when closing.
