help with a confusing error: url-fetch, hash, invalid keyword #vu8

[Robert Vollmert <rob@vllmrt.net>]

Hi,

I’m in writing up some notes on my Guix packaging work earlier this year, and
am running into an unexpected problem that I’m lost with. A concrete example:

$ guix import hackage ormolu > ormolu.scm

add missing imports at the top of ormolu.scm:

(use-modules (guix packages))
(use-modules (guix build download))
(use-modules (guix build-system haskell))
(use-modules (guix licenses))
(use-modules (gnu packages haskell-xyz))
(use-modules (gnu packages haskell-check))

$ guix build -f ormolu.scm

This is with my guix install from roughly July, which has some modifications,
so it’s not impossible that that’s involved, but I don’t see any relevant changes.
And generally the install still works fine, including building some local
custom packages that don’t do anything differently that’s obvious to me.

I suspect I made some simple mistake with imports or my guix package invocation —
hoping someone can provide a hint?
