use "configure" with no optiobs first. If it doesn't find the MPI
libraries, they are in some nonstandard place, in which case,
YOU have to know where they are.

Maybe. -L/directory/where/mpich/libraries/are -lxyz will
find /directory/where/mpich/libraries/are/libxyz.a (or .so
if it is a shared library)
