Hmm. I see Org-9.5.5 in package--builtins even after I removed it from
/usr/share/emacs/elpa (well, hid it in /usr/share/emacs) to try to see
to see if I could local install Org-9.7.6 (which seemed to work).  How
did package--builtins find 9.5.5 ?!?

Ah, yeah.  The manual your pointing to is for Emacs 29.2 while I'm at
28.2.  I'll have to look at Debian backports to see if I can install an
Emacs v29 in bookworm.  Building Emacs from scratch myself winds up
loading too many dependent system software which overloads my small
diskspace on my Chromebook.

Don't remember the specifics, but I believe it had something to with
org-compat.el and that the builtin org-compat was being loaded before
the new Org was loaded and, therefore, interfered with the load of the
new Org.  Org-compat is supposed to avoid this, but an update to Org
broke it.  My hack was to remove the old Org instead of waiting for the
fix.
