Issues building older versions of Guix

[Christopher Baines]

Hey,

I've run in to some confusing issues building older versions of Guix
using a more recent version of Guix.

Take the following example.

(use-modules (guix packages)
             (guix git-download)
             (gnu packages package-management))

(package
  (inherit guix)
  (version "test")
  (source (origin
            (method git-fetch)
            (uri (git-reference
                  (url "https://git.savannah.gnu.org/r/guix.git";)
                  (commit "8db8bf921d2749e35f7e190362e0fc73133a7c5f")))
            (sha256
             (base32
              "1bf3q0a6bvbg28yf11irrln68ad20np2h1i4bh3zv8gjfl1lmlw9"))
            (file-name (string-append "guix-" version "-checkout")))))

When I build this, I get the following errors that appear towards the
middle of the output.

Any ideas as to what this means? It seems to only happen when I build
the older package with a recent version of Guix. If I switch back to an
older version of Guix it seems to work fine.

Thanks,

Chris
