Sounds nice, until I get to here:

"Spack uses RPATH linking so that each package knows where to find its

rpath usage gets into trouble in the difference between develop and
deploy - I may have the built libraries in a build area when I'm testing
code, and that's going to be the wrong place for a deploy scenario where
the libraries should be in standard places (y'know, /lib, /opt/lib,
etc). and vice versa: if I'm testing new versions of libs, I don't want
the rpaths pointing to standard locations because then I'm not picking
up the experimental new versions.

And then there's no rpath at all on Windows, so this part of the concept
is pretty much dead in the water for us.
