I don't get the errors from Dorsal. The error is when I build
everything except DOLFIN with Dorsal, then build DOLFIN against that
build with cmake.local.

What happens then is Python applications (not C++ which are working
fine) fail with this error:

This goes away if I rebuild DOLFIN with the RPATH=OFF option, or if I
build everything including DOLFIN with Dorsal (since Dorsal adds the
RPATH=OFF option).
