Actually, after re-reading the old exchange more carefully, it seems that I already had (require 'ox-org) in my startup file, but
still got the error. However, manually loading the ox-org library avoided the error.

So it seems that:

 1) the cause of the problem was never identified,
 2) manually loading ox-org avoids the problem, and,
 3) I guess I just haven't been using org-mime-org-buffer-htmlize on this machine for a while, so I forgot about it.

Interestingly, this all works with no problems on my other MacBook.

Thanks,
