In order to use MPICH, you need to ensure that PATH and LD_LIBRARY_PATH are consistent and point to the same installation location. If you used the OpenFOAM install instructions here: http://www.openfoam.org/download/source.php - you likely have conflicts with their MPI recommendation.

I have followed the instructions while building and installing mpich. I didnt face any problem in that part. Its just after compilation that this error message occurs. Vinod

It's best to go through the README for step-by-step instructions on how to build mpich.

You seem to be mixing MPICH and a different MPI implementation (probably Open MPI).
