This fixes this very issue for me too. However, all the following
commands are still failing:

guix package --help|head -1
guix package --version|head -1
guix pull --version|head -1
guix pull --help|head -1

and basically all the commands using show-version-and-exit. Do you need
a more systemic approach?

Thanks,

Mathieu
