(gnu scripts environment) imports (gnu packages bash), so we end up
loading a big bunch of (gnu packages =E2=80=A6) modules.

The problem is that (gnu packages commencement) refers to (gnu packages
bash) from its top-level.  But here, we are loading (gnu packages bash)
first, which somehow entails loading (gnu packages cross-base), which
loads (gnu packages commencement), which sees a (gnu packages bash)
module containing zero bindings.

What=E2=80=99s unclear to me though is why (gnu packages cross-base) gets l=
oaded
in the first place.

Could you investigate in that direction?

Thanks in advance,
Ludo=E2=80=99.
