Brian, Thank you for the help. I did include path to orted in my .tcshrc file on mac2, but I put the path at the end of the file. It is interesting that when I logged into mac with ssh, the path was included and orted was in my path. But when I ran "ssh mac2 which orted", orted was not found. It finds orted only after I move the path from the end of .tcshrc to the beginning of the file. Strange. Again, thanks and at least I may make MPI work.
