I have what I think would be a simple use of inferiors, but it is failing to build. I'd like to understand both (1) why and (2) how to get a more informative error message.
```
philip@bastet:/tmp$ cat demo.scm
(use-modules
(guix channels)
(guix inferior)
(ice-9 match))
(define glibc-2.23-channels
(list (channel
(name 'guix)
(url "https://git.savannah.gnu.org/git/guix.git")
(commit
;; glibc-2.23 was removed in commit:
