Using the Spooles Cholesky solver via PETSc in serial

I am using PETSc v2.3.1 (patch 9) via the Fortran interface. When I use the
Spooles CHOLESKY solver in serial I get the error:

	MatSetValues_MPIBAIJ_MatScaler() line 259 in
	Lower triangular value cannot be set for sbaij format. Ignoring
these values, run with -mat_ignore_lower_triagular or call
	MatSetValues() line 827 in src/mat/interface/matrix

The command line option works fine but when I try to use MatSetOption() with
the MAT_IGNORE_LOWER_TRIANGULAR flag I get the error:

	This name does not have a type, and must have an explicit type.

Can you tell me if use of the MAT_IGNORE_LOWER_TRIANGULAR flag is supported
in the Fortran interface for MatSetOption()?
