Hello Guixers

I'm in the process of adding a package to guix. When starting the build 
with ./pre-inst-env guix build openfoam-org I get the error:

error: tcc: unbound variable
hint: Did you forget a `use-modules' form?

Throw to key `unbound-variable' with args `("resolve-interface" "no 
binding `~A' in module ~A" (shared-mime-info (gnu packages gnome)) #f)'.

when removing the module gnu/packages/engineering.scm from the 
use-modules list the error disappears but I can't obviously not build 
the package without this dependency (cgns).

The package builds fine otherwise (inside another channel).

What I am doing wrong here?

Reza
