LAM/MPI 7.1.2-10 (included in F8 from F7, as I saw) Compiled whith LAM/MPI code, includding examples from off. site, does not work in multithread form. I think, it's version problem as far package was not rebuilt for F8. New version of package for RHEL4 from off. site while installed on F8 work whithout errors.
Rebuilt and updated at the same time.

/usr/lib/lam/bin/mpirun /usr/lib/lam/bin/lamboot Is following path is correct?
Yes. It is intended for you to use the environment-modules package to select lam for your default MPI implementation if that's the one you wish to use. Once you have the environment-modules package installed, doing something like adding this: module load /usr/lib/lam/lam.module to any user's .bash_profile (or other personal shell startup script) will be sufficient to get the proper paths you need added to their environment setup.
