Thanks for the explanations.

Instead of,

    guix build $(guix package -A ^julia-)

I use

   guix build -m julia-packages.scm

where julia-packages.scm reads

--8<---------------cut here---------------start------------->8---
(use-modules (guix build-system julia)
             (guix packages)
             (guix profiles)
             (gnu packages))


(manifest
 (map package->manifest-entry
      (fold-packages
       (lambda (package result)
         (if (eq? (package-build-system package) julia-build-system)
             (cons package result)
             result))
       '())))
--8<---------------cut here---------------end--------------->8---


Well, I do not know if it avoids the failure in the “one go” case.
