This was caused by the wrong installation location for the help*.txt files -
they now live in /usr/share/openmpi/help/openmpi, and the 'pkgdatadir' 
configuration option tells the libraries where to find them.

Another problem was with the libmpi shared libraries - these used to live in
/usr/lib/libmpi* .  Having lam and openmpi both install /etc/ld.so.conf.d/*.conf
files meant that the LAM libmpi* libraries were always resolved first - 
('l' precedes 'o' alphabetically) . 

Now, both lam-7.1.1-11+ and openmpi own a '%ghost' file 
/etc/ld.so.conf.d/mpi.conf ,
which is created as a link to either /usr/share/{lam,openmpi}/ld.conf during 
the '%post' script of both RPMs only if it does not already exist.

openmpi's /usr/sbin/mpi_alternatives now makes /etc/ld.so.conf.d/mpi.conf the
primary alternative:

$ mpi_alternatives display
mpi - status is manual.
 link currently points to /usr/share/openmpi/ld.conf
/usr/share/openmpi/ld.conf - priority 50
 slave mpiCC: /usr/bin/om-mpic++
 slave mpic++: /usr/bin/om-mpic++
 slave mpicc: /usr/bin/om-mpicc
 slave mpiexec: /usr/bin/om-mpiexec
 slave mpif77: /usr/bin/om-mpif77
 slave mpirun: /usr/bin/om-mpirun
/usr/share/lam/ld.conf - priority 50
 slave mpiCC: /usr/bin/lam-mpic++
 slave mpic++: /usr/bin/lam-mpic++
 slave mpicc: /usr/bin/lam-mpicc
 slave mpiexec: /usr/bin/lam-mpiexec
 slave mpif77: /usr/bin/lam-mpif77
 slave mpirun: /usr/bin/lam-mpirun
Current `best version is /usr/share/openmpi/ld.conf.
 
I've uploaded the new openmpi-1.0.1-1.fe5 and lam-7.1.1-11 RPMs to 
http://people.redhat.com/~jvdias/openmpi .

Unless there are any objections, I'll import openmpi-1.0.1-1.fe5 into 
FC5 Extras tomorrow. Please try out the new RPMs - thanks!
