Re: mpicc and mpif77 under LAM
I agree that this is probably not a problem of PelicanHPC, but one of getting the options set properly. Probably asking users of the code for help, or asking on the LAM/MPI mail list might help.
Also, Open MPI is pretty well tested by now, so you might want to try it out. You can use update-alternatives to select Open MPI instead of LAM/MPI as the default.
Good luck!
