I think PETSc changed the option name from "-pc_factor_mat_solver_package" to "-pc_factor_mat_solver_type", which I guess is the issue here.
Also, you can use "-ksp_view" on the command line to get a printout of the solver options that were used by PETSc, so you can see if it actually used MUMPS or superlu.
