Hi Douglas,
Thanks for the pointer but that doesn't help me much. I guess setting up the 
library paths are not enough, I have to inform about the include path also 
since the complaints was basically "unable to find mpi.h"

Along the way, here is the mpCC_r script of IBM (this is the thread safe, 64 
bit version, mpCC is almost similar without the "_r" suffix in the 
libraries ):
