As it turns out, only -lmetis is needed from Scotch 5.0.6 onward (in Debian). However, it looks like Scotch only implements a small subset of the METIS interface. It's enough for libMesh and deal.II, but Elmer needs a couple of functions it doesn't provide (METIS_PartMeshNodal and METIS_PartMeshDual).
