Okay; sorry for that.

mpif90 said that there was no f90 compiler configured for MPI.  This 
obviously was the problem, so thank you for that hint.  It now 
compiles perfectly.

But now, the next problem is that I am not able to use MUMPS.  As 
described in the manual, I start my application using

-ksp_type preonly
-pc_type lu
-mat_type aijmumps
-ksp_monitor

and I get

[0]PETSC ERROR: MatLUFactorSymbolic() line 1940 in src/mat/interface/matrix.c
[0]PETSC ERROR: No support for this operation for this object type!
[0]PETSC ERROR: Matrix type mpiaij  symbolic LU!

[0]PETSC ERROR: User provided function() line 396 in unknowndirectory/src/numerics/petsc_linear_solver.C

What is wrong?

Best Regards,

Tim
