I recently tried to upgrade the packages on my desktop that are
installed through Guix, and Ansible is failing to build. (I've attached
the build log to this report.) I went looking for the cause, and it
looks like... the 'wrap' phase is failing because there's no 'sbin' path
in the store dir. I tried to fix that by accounting for that case in the
Python build system: https://issues.guix.gnu.org/issue/37722

However, even after that, the 'fix-symlinks' phase (defined in the
ansible package itself) is failing:

starting phase `fix-symlinks'

This leads me to believe that the problem may have been introduced
somewhere else and that there *should* be an 'sbin' dir in that store
dir. (Although I can't see the full path in that backtrace as the string
is truncated.)

I'll keep digging, but I figured I'd post here in case anyone with
deeper knowledge of the build flow has a better idea of what's wrong.
