Here are the extracted sources for cksum.  You will probably need to
modify this on most systems.  But for what its worth...
#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of archive 1 (of 1)."
# Contents:  cksum cksum/cdefs.h cksum/cksum.c cksum/crc.c
#   cksum/extern.h cksum/print.c cksum/sum1.c cksum/sum2.c
