Color does not understand *= #1
Description
Setup: Cuis5.0-4191 on Windows 10 with Math 3D package installed from Numerics repo
Hello, I'm new to Smalltalk in general and Cuis in particular so I'm pretty certain that I am just missing a package, but after cloning this repo and adding the RayTracer and RayTracer example packages when I try RayTraceExamples example1 I get Color(Object)>>doesNotUnderstand: #*=
On the off chance it is a bug somehow I'd be happy to try to fix it as a learning exercise if you could perhaps give me a clue of where to start.
Thank you!
