[Cuis-dev] Cuis on macOS - Dynamic loading of Homebrew libraries

[Juan Vuletich]

Hi Jon,

(what follows is a clarification that may be useful for anybody using Cuis)

We may discuss this particular issue offline or here in the mail list. 
No problem.

The Cuis community is informal, relaxed and friendly. Every kinds of 
explorations are welcome. Multiple points of view help us grow our 
collective understanding.

Besides, anybody is most welcome to post any code or stuff to this mail 
list, or publish elsewhere. It is only when we push stuff to the main 
repo or other Cuis-Smalltalk GitHub Organization repos, that we need to 
be careful that the stuff does good (at least) to most people, and to 
the ongoing evolution of Cuis.

Thanks!
