Nice catch!

Would it be overkill to avoid this for target-hurd?, someting like

      (use-modules (guix utils)
      ;; ...
      (specifications->manifest
       (if (target-hurd?)
           '()
           (list "imagemagick"
                 "perl"))

Maybe it's premature; as I'm not even sure if fails to builds natively;
some of its dependencies don't cross-build, but it may just build on the
Hurd?  I haven't built a guix checkout in a childhurd for some time...

Greetings,
Janneke
