Problem is that the grafting code (‘graft-derivation/shallow’ in (guix
grafts)) is running in the C locale, so it expects file names to be
ASCII.  I’ll look into it.

Some comments on the package:

Is this really needed?  Perhaps leave a comment explaining whether/why
“make check” at the top level is broken (and perhaps report it as a bug
upstream!).

This is not needed (or it’s a bug too ;-)).

I think ‘gpl3+’ is enough here since it “wins”.  You can leave a comment
explaining where the other licenses appear, though.

Thanks!
