never used it but i'll guess based on your error:

mpicc -I /usr/local/mpi/include -L /usr/local/mpi/lib hello.c

if that fails to work (and the box has been on overnight since the mpich
install), you might want to try

    locate libmpi

if the box hasn't been on overnight either update locate's db or run

    find /usr/local -name 'libmpi*' -print
