Stephen,
This was an error in our last release and did not properly fixed
in a patch (why?). It will be in the next release.
You can edit include/finclude/petscmat.h and add
PetscEnum MAT_USE_COMPRESSEDROW,MAT_DO_NOT_USE_COMPRESSEDROW
PetscEnum MAT_IGNORE_LOWER_TRIANGULAR,MAT_ERROR_LOWER_TRIANGULAR
PetscEnum MAT_GETROW_UPPERTRIANGULAR
parameter (MAT_USE_COMPRESSEDROW=89)
parameter (MAT_DO_NOT_USE_COMPRESSEDROW=90)
parameter (MAT_IGNORE_LOWER_TRIANGULAR=91)
parameter (MAT_ERROR_LOWER_TRIANGULAR=92)
parameter (MAT_GETROW_UPPERTRIANGULAR=93)
then it should work properly.
