bug#64302: Guix derivation cannot be computed during pull

[Andreas Enge <andreas@enge.fr>]

Hello,

here is what happens on a server I do not manage to update for about a year now:

$ guix pull

Here is the content of the compute-guix-derivation script:

If I remember well, in the past I tried to update with a guix from guix
(obtained with "guix install guix") and also with one from git
("./pre-inst-env guix pull"), and the result was always the same.

So here is the sad outdated state:
$ guix describe
