For historic reasons, you have to activate parallelism actively by
providing --enable-parallel to configure. If your MPI installation is
in a non-default location, you migth have to provide the executables
with MPICC in addition

A convenient way is using an options file, that you provide to
dunecontroll with --opts=<filename>.

Here is an example file:
# use these options for configure if no options a provided on the cmdline
CONFIGURE_FLAGS="--prefix=/home/mblatt/dune_install
--disable-documentation --enable-parallel CXX=g++ CC=gcc
MPICC=/opt/openmpi/bin/mpicc MPICXX=/opt/openmpi/bin/mpicxx
CXXFLAGS=\"-O0 -g -Wall\" CFLAGS=\"-O0 -g -Wall\""
MAKE_FLAGS="all"

BTW: This and many other useful things should be documented in the
buildsystem howto.

Cheers,

Markus
