A minor update. I was able to reproduce this problem in a Guix
environment. If I install guile in the environment, this problem does
not manifest. If I don't have guile in the environment, this problem
manifests.

In other words, with

guix environment --ad-hoc guile autoconf automake pkg-config

this problem does not manifest. But, with

guix environment --ad-hoc autoconf automake pkg-config

this problem manifests. I have no idea why this is the case, but perhaps
this could be a lead worth investigating.
