[MPICH] MPICH2 with mumps error in a call to MPI_Bcast (INVALID DATATYPE,Invalid communicator)

[William Gropp]

The value of the communicator indicates that MUMPS was probably  
compiled with the wrong mpi.h - the value of MPI_COMM_WORLD is very  
different from 0x5b.  Make sure that your include path selects the  
MPICH2 include directory.
