Quick test, it seems like 
  CXX=CC scons configure customCxxFlags="-DHAS_MPI=1" customLinkFlags="-lmpi++ -lmpi"

fails since CXX isn't found in mpi_cxx_compilers


 if env["enableMpi"]:                                                                                                    
    mpi_cxx_compilers = ["mpic++", "mpicxx", "mpiCC"]                                                                     
    mpi_cxx = os.environ.get("CXX", env.Detect(mpi_cxx_compilers))
