[petsc-users] Mumps giving huge volume of output

I have just successfully compiled PETSc with

./configure --with-cc=mpicc --with-fc=mpif90 -with-cxx=mpicxx
--prefix=/home/santiago/usr/local --with-make-np=10
 --with-shared-libraries
--with-packages-download-dir=/home/santiago/Documents/installers/petsc
--download-fblaslapack --download-mumps --download-scalapack
--with-debugging=0 COPTFLAGS='-O -O3 -march=native -mtune=native'
FOPTFLAGS='-O -O3 -march=native -mtune=native' CXXOPTFLAGS='-O -O3
-march=native -mtune=native'

When I run my program, I get very large amounts of information from mumps.
For example, the first such block starts with

    Entering DMUMPS 5.2.1 from C interface with JOB, N =   1          15
          executing #MPI =      8, without OMP

     =================================================
     This MUMPS version includes code for SAVE_RESTORE
     =================================================
    L U Solver for unsymmetric matrices
    Type of parallelism: Working host

     ****** ANALYSIS STEP ********

     ** Max-trans not allowed because matrix is distributed

    Entering analysis phase with ...

Is there a way to control (and eliminate) that output?
I guessed with --with-debugging=0 would do the trick, but that was not the
case.

Thanks,
Santiago
