Aha! But then it doesn't work fine.

What happens is that the first time, SWIG exits with an error (after
partially completing dolfin_wrap.cpp) and then make also exits with an
error. The next time you run make, make will see that dolfin_wrap.cpp
is up to date and won't run SWIG. So it looks like it worked but it
really didn't...

I think you need a newer SWIG.
