1. Copying petscarch to configarch in /usr/lib/petsc/bin
2. Applying the attached patch to configure. It now eliminates the need
to use petsc's main makefile.
3. Run configure with PETSC_DIR set to /usr/lib/petsc

As I know very little about the autoconf stuff, I just patch configure.
Please let me know if I make any mistakes. I hope to learn more.

Regards,
ST
