At the end, I need to do:

    ./pre-inst-env guix build webkitgtk -S --no-substitutes

but I do not necessary want to rebuild all.


Well, all in all, I agree with Maxime that the backtrace is ugly, the
message misleading and last that various options should be tried
automatically (for fixed-outputs).


Cheers,
