Applied, but this raises the question of whether $SED in make.sh is still
needed? (I applied a patch from a macos dev who said it worked, I had a mac but
my apple store subscription was so screwed up an hour from a mac expert who knew
where the secret hidden error logs were couldn't get it unborked. I break
everything. Anyway, there patch used "gsed" instead of "sed", which is gnu sed.
The above wasn't using that because I forgot. :)

If we don't need gsed, then $SED should probably be removed...
