Re: [BUG] New error: (void-function org-url-p) when exporting to LaTeX [9.4.6 (9.4.6-gc5573b @ /Users/stanton/.emacs.d/straight/build/org/)]

[Tim Cross <theophilusx@gmail.com>]

Unfortunately, I don't know anything about straight.el. However, I note
that the very first line of your grep is a line from the org-compat.el
for version 9.5, so you are still getting mixed versions.

My guess is that straight.el is installing from the master branch of the
org repo rather than the maint branch. You then also install the contrib
package from non-gnu ELPA, which has a dependency on org (the ELPA or
orgmode.org version, which is 9.4).

My advice would be to not use straight.el and just use the org package
from ELPA (which will be in sync with the contrib package from nongnu
ELPA) or use striaght.el for both org and contrib or ensure straight.el
is using the maint branch and not the master branch.
