Can you try the attached patch with the MVPAICH2 0.9.8 source code? This
modifies the mpicc.in, mpif77.in, mpif90.in, and mpicxx.in files to put
the MVAPICH2 installation include directory before anything else. It
should be all right to do this in all cases.

What I was saying before in reference to the standard include define
doesn't matter. Once the compiler has found the proper include file,
it's not going to search for it again or anything - and with this
change, it should be checking the MVAPICH2 installation include
directory first no matter what.

Nathan, I am not sure if this will help you - but maybe you can try it
as well. This has the same effect as editing the already built compiler
commands in the same way... the context should be clear from the patch,
so you both could try that as well.
