Investigate hdf5+mpi

[chapman39]

PETSc cannot build with +hdf5 due to requiring it built with mpi. Serac set hdf5~mpi a long time ago, so it may not be an issue anymore. This would in turn allow LiDO to build petsc+hdf5 as well.

On trying this, petsc failed to install. This is from petsc's configure.log:
