Wow, I'm amazed... it just works "out-of-the-box" configured with
with-openib. I guess the new kernel supplies everything I need.
Thanks a bunch for the clues.

In general, you need a functioning IB subsystem on your machines for
OMPI to build for and use IB. This includes both the set of kernel
drivers and the userspace libraries. In particular, Open MPI v1.2
uses the "ibverbs" library. If OMPI can find the ibverbs library and
headers during it
Brian,
Here is how I do it:
./configure --prefix /opt/openmpi-1.2.4 --with-openib=/usr/local/ofed \
--without-tm CC=icc CXX=icpc F77=ifort FC=ifort \
--with-threads=posix --enable-mpi-threads
