I'm not quite sure what you mean here -- you said that you're able to
run LAM but then not able to run LAM... Do you mean that you are able
to run LAM commands with no problem, but then cannot run MPI
applications that were compiled with LAM?

Besides liblamf77mpi.so, what else is missing?

liblamf77mpi.so is part of LAM, but LAM is distributed by most Linux
distributions. So it depends on how you installed LAM -- there are
typically 2 options: 1) compiling from a source tarball from the LAM
web site, 2) installing an RPM (or set of RPMs) for your Linux distro.
If you compiled LAM yourself from a source tarball, then all the
libraries (including liblamf77mpi.so) should be under $prefix/lib. If
you didn't specify --prefix, it defaults to /usr/local. Your
description is not verbose enough to tell if the following is a
problem, but if you chose a non-standard prefix (and possibly even
/usr/local -- depending on how your Linux distro is setup), you may
need to ensure that LD_LIBRARY_PATH includes $prefix/lib (e.g.,
/usr/local/lib) so that the run-time linker can find the LAM shared
libraries.
If you're installing a Linux distro's RPM of LAM/MPI, then I can't say
where that library is -- it's up to whoever made that RPM (i.e., each
Linux distro does it a little differently). Some distros actually
split the LAM package into multiple RPMs (devel, runtime, etc.); you
may need to install more than one LAM RPM.
I'm guessing that you're installing from RPM because LAM source
tarballs build static libraries by default, not shared libraries. You
may wish to examine the list of files contained in your RPM(s) with the
"rpm" command. For example:
rpm -qpl lam-7.1.1-1.i586.rpm
