You don't need PORTREVISION when you are already bumping the DISTVERSION/PORTVERSION

Can you confirm that the author has successfully faced 3 consecutive timeout in bugzilla?

This should be USES=emacs:build

17

python:3.0 is not a valid version. Check Mk/Uses/python.mk for valid versions. Specially the var _PYTHON_VERSIONS

18

This should be set to yes and it will automagically set it to ${PREFIX}/lib

About emacs:build
This yields an error "ninja: error: unknown target 'EMACS=/usr/local/bin/emacs-29.4'" maybe related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251191

I will wait for maintainer time-out

The remaining will be update.

Portclippy : change some order. Pass portlint.
