bug#28144: info-dir ERROR: no code for module (guix build utils)

[Christopher Baines]

I've had the following issue a few times now, it seems that somehow,
the info-dir builder can be incorrectly generated, without the usual
module import stuff.

The most recent time this occurred, I worked around this by finding the
guix package in the store which I thought was being used at the time,
and explicitly garbage collected it (guix gc -d ...). I then rebuilt
it, and this seemed to work around the problem. I was using the same
guix package, pinned to an revision in a git repository.


The builder starts with:

  (begin (use-modules (guix build utils)


This is the error which you get:
