What I was saying was that your application looks like it is at least
somewhat customized for g++, but mpiCC using pgCC underneath to compile
things. So if you change your python makefile from g++ to mpiCC,
you're effectively changing it to pgCC, which your application doesn't
seem to like.
So one way to fix that is to make mpiCC use g++. The best way to do
that is to recompile your MPI to have support for g++ (instead of
pgCC). Note that I said "your MPI implementation" -- it's not clear
that you're using LAM/MPI. See below.

Are you sure that you're using LAM/MPI? "-showme" or "--showme" are
LAM-specific options that will definitely show what command mpiCC is
using to compile your applications. Do you know what version of LAM
you are running?
Do you have the "laminfo" command installed?

It is doubtful.
