Really strange, I started a guix repl and did ,use (guix) ,use (gnu packages simulation) ,build openfoam-org and everything works, but when I do ./pre-inst-env guix build openfoam-org the build fails with the aforementioned error. Any idea what the problem is here? Could anybody try this on their side, the patch is attached to this email.
