Yes, this is _compilation_, and it was successful. However, in order for
the _link_ to be successful, you
will need the PETSc library on the link line. I am guessing that there is a
make variable you must define.

I am Cc'ing one of the people at ETH since I think that place is
responsible for this irresponsible build system.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
