This is very odd behavior. The application code can't find the symbols in
libmpi and libmpi can't find symbols that should be provided by the C++
standard library. This usually means that you're trying to mix compilers
-- using GCC for the app and stdlib and SGI C++ for LAM, or something
similar to that. Actually, changing the version of g++ used to compile
code can have the same problem, as GCC changed the C++ name mangling
scheme a couple of times between GCC 3.0 and 4.0. My guess is that
different versions of GCC are the cause of your problems -- you might want
to recompile LAM to make sure it was compiled with the same version of GCC
you used to compile your application.
