`Divide by zero` and other errors out of the box

[tgecho]

I'm on MacOS with these installed via homebrew:

• Clojure CLI version 1.10.3.998
• Leiningen 2.9.7 on Java 17.0.1 OpenJDK 64-Bit Server VM

I get the following exception when I start following through the tutorial:

$ lein run

It only succeeds when I jump to the step where I run lein run -c config/base.yaml -c butty.yaml

Trying to build lein run -c config/dactyl_manuform/base.yaml also fails with this exception.

This happens on the latest commit (651532cd5bb400666ec5d70ba4dd1cb0dada34a1) as well as the dmote-v0.7.0 tag. I tried going to even earlier tags but started getting dependency errors.

I realized later that I needed to lein run -c config/base.yaml -c config/dactyl_manuform/base.yaml (as per the docs), but it still stands that the first step of the intro will trigger this exception.

Thank you for reporting this. I have traced the problem to scad-tarmi and will release a fix tomorrow.
