there was not more, it was building ok, but this showed straight up on
building DofMapBuilder.cpp

i'm using a self-installed openmpi, and i switched my compilers to point
to gcc4.4.1, but probably my mpicompilers do wrap to the older version

thanks for the hint, Garth and Harish, i'll let you know as soon as i
can fix it.
