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, -pd
