Good you moved it, but see below.

cron/gate_news is trying to create the lock and has no permission to do so.

Normally, the lock would only exist during the few (milli)seconds that
gate_news was running, but in your case it isn't even created.

OK, but there is another crontab somewhere running gate_news.

Also, Mailman's cron jobs should run as the Mailman user (usually
_mailman in FreeBSD/Darwin), not as root.

Since the gate_news entry in the crontab entry you are looking at is
commented out, there must be another crontab somewhere.

You may have a system crontab in /etc/cron.d/ or another user crontab.
Note that the format of system crontabs is different. There is an
additional field between the times/days and the command for the user to
run as.
