If I'm reading that right, we can link it from BSD and LGPL libraries.
Currently MUMPS is in Debian used by
getfem++ LGPL
petsc BSD-2
which is used by dolfin LGPL
trilinos BSD
code-aster GPL2
So there should be no conflict using mumps with CeCILL-C, except
perhaps with code-aster.
Incidentally, SCOTCH is also CeCILL-C, and is already in the archive
(and also used by many of these packages).

wants to fly me to Paris to testify, maybe I can live with that...

Bit extreme to declare entire nation's jurisprudence corrupt. Unless
you mean the court's judgement will be ignored, in which case it
doesn't matter where the court is anyway.
