Uh, because of shared library versioning?  (So dependent packages link
against the proper version, so multiple versions can be installed at the
same time, etc.)  Same as PETSc, libMesh, and just about any other
library package.  Only this interface changes more often than, say,
LAPACK.

Yeah, that's pretty unavoidable.

If the scotch upstream versioned their library interface, it might make
things somewhat simpler, but AFAICT, the interface changes with new
releases.
