libtrilinos-amesos12/12.10.1-3 depends on libmumps-4.10.0 because
libtrilinos_amesos.so.12 is linked to libdmumps-4.10.0.so and
libmumps_common-4.10.0.so

As per debian/control, libtrilinos-amesos-dev depends on any version
of libmumps-dev.

The new version of MUMPS changed ABI in a backward-incompatible way,
requiring a transition in Debian and every package that was built
against libmumps-4.10.0 needed to be rebuilt against libmumps-5.1.1 to
pick up the new dependencies.  See the transition bug #864650 for more
details.

The binNMU of trilinos 12.10.1-3+b1, which was supposed to pick up the
new dependencies, failed to build from source, see:
https://buildd.debian.org/status/logs.php?pkg=trilinos&arch=amd64
and also bug #868523.

Trilinos 12.10.1-4 was built against libmumps-5.1.1 and migrated to
testing on 2017-07-22, see:
