Everything except DOLFIN should be ready for release now. It's
currently failing on the buildbot with

I haven't installed SCOTCH yet, so it fails for me. Is SCOTCH now
default? Does it work with the regular SCOTCH in Debian? How does it
compare to ParMETIS? (Speed, memory usage.) I remember the first time
we tried SCOTCH that it was very intensive on memory usage.

When I change to ParMETIS, assembling works (but is slow) and then
UMFPACK reports a singular matrix.
