Maybe the substitutes are now gone, because I just tried again and the
error looks the same:

https://gitlab.com/debdistutils/guix/container/-/jobs/9042454855

If it got the binary substitutes, I suppose things would be fine.

Looking more carefully at the errors, I notice this part:

   actual-err>    cpack-cfg> set(DPKG_EXECUTABLE "/usr/bin/dpkg")
   actual-err>    cpack-cfg> set(READELF_EXECUTABLE "/gnu/store/pqai4n95zn5wdw430gslb00sb967jdg8-binutils-2.41/bin/readelf")

So for some reason building cmake-bootstrap in guix in Debian picks up
Debian's /usr/bin/dpkg, doesn't it?!

I suppose that Guix's build servers aren't running Debian, so it won't
find any /usr/bin/dpkg.

Maybe this has something to do with why it is only all the DEB-related
cmake self-tests that fails here.

(However it doesn't explain why I couldn't reproduce the same problem on
my own arm64 machine that is running Trisquel.  Maybe substitutes just
happened to be available when I tried it?)

The GitLab run above is in a minimal debian 12 container, and the
commands are essentially these:

  - apt-get update
  - apt-get install -y buildah ca-certificates eatmydata
  - time eatmydata buildah build -t ...

With the Containerfile running essentially this:

set -x && \
cat /etc/os-release && \
locale -a && \
apt-get update && \
apt-get install -y guix netbase && \
(env LC_ALL=C.UTF-8 guix-daemon --disable-chroot --build-users-group=_guixbuild --discover=no &) && \
set && \
(guix pull --url=https://gitlab.com/debdistutils/guix/mirror.git \
 || { cp -v /var/log/guix/drvs/*/*.drv.gz .; gzip -d *.gz; tail -v -n1000 *.drv; false; })
