Jack, this bundling strategy is a distribution nightmare. Suppose that some other package "X" independent of clique also bundles Elemental. How does an application (or another library) use both X and clique?

context:
clique packages metis,parmetis,elemental sources in a single bundle.
So we were attempting to build them separately [from petsc configure].
Jack has extensions to metis and parmetis functionality - thats used
in clique. We tried to split this out into separate -lparmetis-addons
library [using parmetis public includes] so that our current
-lparmetis could be used. But this doesn't work as it needs parmetis
private includes.
So looks like we'll have to add these extensions to the metis/parmetis
tarballs we distribute [and have common metis/parmetis sources
available for both petsc an clique]
