Thanks for the pointer.  I think it was a bad idea to try it with the
pre-inst-env, because before it even got to this point I had to modify
the location of guile in the header of scripts/guix.

So, maybe I shouldn't be using the pre-inst-env at all and just
properly install the patched version.  I can always --roll-back anyway.

So I applied the patch, and ran:
make dist

Which produced a tarball.
I then modified the guix recipe to use the tarball instead of a git
checkout.  But unfortunately, building it is again troublesome:

Some deprecated features have been used.  Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information.  Set it to "no" to suppress
this message.

Why does Guix need Shepherd?  And if it needs the (charting)
module, why isn't guile-charting already an input?

If I could get this to work, then I could use this mechanism in the
future too, to test patches on our cluster before they end up in
upstream.

Kind regards,
