I cloned a new version and it doesn't work.Deep in the output when
compiling DOLFIN I do get the warning message


*** Warning: Linking the shared library libdolfin.la against the
*** static
library /usr/local/lib/petsc-2.3.1-p14/externalpackages/spooles-2.2/linux-gnu-c-real-debug/MPI/src/spoolesMPI.a is not portable!

I didn't configure Spooles by hand. I just let PETSc download and
configure it. This could be the problem.
