    We removed the interface to sparsekit a long time ago, because it wasn't very good. 

    If you want to use ILUT you can use --download-hypre then run with -pc_type boomeramg -pc_hypre_type pilut 

    See http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-dev/docs/manualpages/PC/PCHYPRE.html for more details and run the PETSc program with the above options and -help to see the various pilut options.
