OK, I've now imported openmpi-1.0.1-1 into rawhide (it remains to be seen 
whether it will make FC-5) . The SRPM and i386 RPMS are at:
   http://people.redhat.com/~jvdias/openmpi/

Please test this out and let me know of any issues ASAP - thanks .

I've also built lam-7.1.1-10.FC5, with the suggested changes - it should be in
tomorrow's rawhide - the srpm is also at the people page above.

LAM headers now all live under /usr/include/lam , libraries under /usr/lib/lam,
and man-pages in /usr/share/lam/man .

There are directory structures that could be used for environment-modules in 
/usr/share/{lam,openmpi}/{bin,lib,include,man}, and an attempt at module files
in /usr/share/{lam,openmpi}/*.module.

The binaries which clash between lam and openmpi are shipped named with a
prefix that differentiates them:
  /usr/bin/{om-,lam-}{mpirun,mpiexec,mpicc,mpic++,mpiCC,mpif77}

By default, the lam package creates links to its /usr/bin/lam-* files, without
the 'lam-' prefix - it will still be the default MPI implementation.

There are now pkg-config files for lam and openmpi, and openmpi now contains
an /usr/sbin/mpi-alternatives script that can be used to create alternatives 
for lam / openmpi:

$ pkg-config --libs --cflags lam
-I/usr/include/lam  -L/usr/lib/lam -lmpi
$ pkg-config --libs --cflags openmpi
-I/usr/include/openmpi  -L/usr/lib/openmpi -lmpi
$ mpi_alternatives
Usage: mpi_alternatives < install | display | remove | set>
    Sets up alternatives for MPI (Message Passing Interface) between LAM and
OpenMPI implementations.
$ mpi_alternatives install
$ mpi_alternatives display
