Problem building against PETSc dev version

[Chris Richardson]

PETSc interface to KSPSetOperators() has changed in the dev version of PETSc, so it does not have a fourth argument (enum of non_zero_pattern). This is found in PETScKrylovSolver.cpp and PETScLUSolver.cpp in set_petsc_operators()

[Prof Garth Wells]

Should have been fixed in 0e8bf86.

[Chris Richardson]

Yes fixed already.
