Barry,

Or default install is approximately equivalent to '--prefix=PETSC_DIR' - so paths
hardcoded paths to the libs are 'PETSC_DIR/lib/$PETSC_ARCH'

If --prefix option is actually used [which also requires a make install] - then
the hardcoded paths would be '$PREFIX_DIR/lib'

Don't see a need for additional option '--with-install-directory'
