I guess --no-grafts is not sufficient, and I need to use it, and additionally 
install one of the two packages you mentioned. Merely adding --no-grafts still 
results in the error:

I installed those 2 packages and tried running like before, which results in a 
new, different error, but I am not sure what it means to "run from my profile 
bin dir", so I did not take any steps towards that:

Can you explain further, how to do the "run from my profile bin dir" part?

What does it mean to "wrap" G-Golf applications?

All I want to do is run the code, and see some GUI shown on my screen. (And then 
be able to change things in the code, run it again, seeing the changed GUI, etc. 
Development workflow.) Is that already requiring to "wrap" it?

If the developed program runs on another machine that has Guix installed, then I 
am already satisfied (for now). I have not thought about shipping or something 
like that at all yet. Even less about making the developed program another guix 
package.
