I don't like that, having a dependency that could be easily removed for
a script most people probably don't use.

That's a better solution, and easy to do in FreeBSD ports.

Or simply make the script more portable e.g.

if [ `which md5sum` ] ;then 
   MD5='md5sum | sed "s/  -//"'
elif [ `which md5` ]; then
   MD5=md5
fi
...
md5=$(printf "%s" "${rndseed}${i}" | $MD5
