This was my point about building things in a different tree.  I do this 
with tools I use in https://github.com/joelandman/nlytiq-base , which 
gives me a consistent set of tools regardless of the platform.

Unfortunately, some of the software integrates Conda, which makes it 
actually harder to integrate what you need.  Julia, for all its 
benefits, is actually hard to build packages for such that they don't 
use Conda.

Yeah, this has become common across many fields.  Containers become the 
new binaries, so you don't have to live with/accept the platform based 
restrictions.  This was another point of mine.  And Greg K @Sylabs is 
getting free exposure here :D
