Gems can be used to installing anything. It often build java, go, C, C++ and I think I heard it could do rust once, but generally anything in faster languages to create faster versions of the implementation of the functionality for a given gem. I bring that up to highlight some of the wrong assumptions you make. You make several needless assumptions and use those to draw funny distinctions between things. I am not even sure of the point anymore. likely any of these systems could be used in a variety of environments for a variety of purposes.
