Works fine here too. I also think it looks pretty good. Something I
like is that it looks like I will be able to contribute myself to
keeping the config files in good shape. I didn't really want to touch
them before (because of their size and complexity).

I guess we would also need to provide Makefiles instead of SConstruct
for all the demos.

We could have one demo demo/build/cpp which contained various ways to
build against DOLFIN, including plain Makefiles, SConstruct and
possibly other options.

The next step will be to add support for generating the pkg-config
file for DOLFIN.

Btw, I set build directory = install directory = pwd/local. Is that
good practice or is there a reason for separating build directory from
installation directory?
