naturally this isn't going to work

MPinc = -I$(MPdir)/include
*MPlib = $(MPdir)/lib/libmpi.a*
Is there a reason you are trying to link with a static libmpi. You
really want to link with libmpi.so. It also seems like whatever
Makefile you are using is not using mpicc, is that true. The reason
that is important is mpicc would pick up the right libs you needed.
Which brings me to Ralph's comment, if you really want to go around the
mpicc way of compiling use mpicc --showme, copy the compile line shown
in that commands output and insert your files accordingly.

because that doesn't exist

is what I have for listing *.a in the lib directory. none of those
are equivilant becasue they are all linked with vampire trace if I am
reading the names right. I've already tried putting
/opt/SUNWhpc-O/HPC8.2.1c/sun/lib/libvt.mpi.a for this and it didnt
work giving errors like

Something looks fishy about your numbers. The first two sets of
numbers look the same and the last set do look better for the most
part. Your mpirun command line looks weird to me with the "-mca
orte_base_help_aggregate btl,openib,self," did something get
chopped off with the text copy? You should have had a "-mca btl
openib,self". Can you do a run with "-mca btl tcp,self", it
should be slower.
I really wouldn't have expected another compiler over IB to be
that dramatically lower performing.

also, I'm not sure if I'm reading the results right. According to
the last run, did using the sun compilers (update 1 ) result in
higher performance with sunct?

some tests I did. I hope this isn't an abuse of the list.
please tell me if it is but thanks to all those who helped me.
this goes to say that the sun MPI works with programs not
compiled with sun’s compilers.
this first test was run as a base case to see if MPI works.,
the sedcond run is to see the speed up using OpenIB provides
