I guess you aren't interested in the advice given you by
your linker. 
Doesn't it look like your build of lam installed in
/usr/local/ was 
built with a different architecture switch (e.g 64-bit)?

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.
