If I understand well, this sequence:

  cd ~/guix-master
  git checkout <hash>
  cd /path/to/project
  ~/guix-master/pre-inst-env guix environment -C tool --ad-hoc other tools

is nouw somehow equivalent to:

  guix pull --commit=<hash>
  guix environment -C tool --ad-hoc othertools

Right?

In fact, the question is how to do when a package (gwl) depends on
Guix the library.
Kind of build time vs run time. If I understand well.
It was my initial issue: gwl was built with a version of Guix. Then it
fails at run time because the very Guix version was incompatible.


All the best
