I got it to work, but it didn't have anything to do with the environment variables on the shell.
I am running CentOS 4.2, and the system has everything compiled with the GCC 3.4, and it also has GCC 4.0 installed. I was building ompi with GCC 4.0, and I think it was having trouble with loading dynamic libraries since the system is build with 3.4. I am not sure if that is exactly the case, but I recompiled ompi with GCC 3.4, and only used gfortran for FC. After that things seemed to be working properly. Was my guess correct, or do you know the real reason why this is? Also, does ompi have something similar to "lamboot" and "recon", or is the only option is adding --hostfile or --host a,b to the mpirun command?

Also, I don't think ~/.bashrc is read on a noninteractive login.
