A few notes:
- We actually recommend against setting the LAMHOME environment variable
except in very rare circumstances. From what you described above, you
shouldn't need to set it. Don't get me wrong -- setting it won't cause
any problems, but if you don't need it, you shouldn't set it, and it
eliminates one set of potential problems.
- You only need to add /usr/lam-7.0/bin in your PATH -- you don't need to
add the lib and include directories into your PATH.

Two notes:
1. I think your problem may be the --with-FFLAGS -- it should actually be
--with-fflags. The switch is case-sensitive; you --with-FFLAGS switch was
probably ignored.
2. Most modern versions of ssh don't require the -x flag anymore. That
was mainly for older versions of ssh that required the use of "-x" to make
ssh *not* send a message to stderr about X forwarding. You should
probably be able to use --with-rsh=ssh (make sure you use two dashes
before "with").

Give the above a try and see if that fixes your problems. If it does not,
send some specific output about what happens when you try to compile/link
MPI programs, as well as the output from "laminfo" and "mpif77 -showme".
