I built this on Arch. You could make a copy of your liblua file and rename it to what the game expects, that should work

I found that Ubuntu needs the "libsdl2-ttf-2.0-0" package:
sudo apt install libsdl2-ttf-2.0-0
I tried using LD_PRELOAD on all of the Lua shared library objects and nothing matched. Preloading libraries looks like this:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/liblua5.3.so.0 ./mooncommander
I couldn't figure out how to run this game on my Ubuntu 18.10 variant.
