It looks you are calling Metis routines directly. In that case, you can do one of two things
1) use the additional PETSc ./configure option -download-metis-use-doubleprecision=1 or 2) ensure that the arguments such as tpwgts that you pass in are not PetscScalar but instead float. This would require changing your code slightly.
