Org mode update breaking build?

[Tobias Bading <tbading@web.de>]

Grrr. Is it normal that Org updates break builds?

I had a Git worktree with a clean checkout and build of Emacs 29 —
933705d61e according to the reflog. Just now I fetched the latest Emacs 29
changes and tried to build 21ec6c1d5c using the usual “nice make -j4”,
resulting in a *huge* wall of text. Something along the lines of

--- %< ---

Warning (emacs): Org version mismatch.  Org loading aborted.
This warning usually appears when a built-in Org version is loaded
prior to the more recent Org version.

Version mismatch is commonly encountered in the following situations:

[…]

In toplevel form:
org/ob-core.el:31:2: Error: Org version mismatch.  Make sure that correct ‘load-path’ is set early in init.el
make[3]: *** [Makefile:332: org/ob-core.elc] Error 1
make[3]: *** Waiting for unfinished jobs....

--- >% ---

A “git clean -fdx -e .ccls-cache -e compile_commands.json -e TAGS” plus
“./autogen.sh” plus “configure […]” plus “nice make -j4” later I have a
working clean Emacs 29 again.

But of course the same happens again in my hacked worktree. So this time I
try “make distclean” for a change — plus the whole autogen, configure,
make aria again. And guess what… the error is still there!

Is that normal? Why is snowflake Org breaking GNU Make?
