Thanks Dirk; I think the issue was that with other MPI implementations
also installed, the alternatives symlinks pointed to them, but my
package tells Salomé to look in /usr/lib/openmpi/include for headers.
So it was getting mpi.h from OpenMPI and failing to link with lam and
mpich.
Not a problem in general. We're both using 1.2.5-2 in unstable.
