This comment was about my problems as an Erlang newbie with getting the demo to run on macOS.

I finally got it to work, so for anyone interested, here are the necessary steps:

```erlang
brew install sdl2
brew install sdl2_ttf
brew install sdl2_image

git clone https://github.com/rvirding/ship-demo.git
cd ship-demo

git clone https://github.com/rvirding/luerl.git 
cd luerl
make
cd ..

git clone https://github.com/ninenines/esdl2.git
cd esdl2
make
cd ..

make

vi run.sh [Set paths to elib/ directories in DEMO_LIBS]

./run.sh

```
