I got the same error message after moving my /var/tmp to a different
disk and making the link.  The solution so you don't get this message
every day is to change the tmpwatch line to use the actual path name.
Mine is:

/usr/sbin/tmpwatch 240 /tmp /scr/var/tmp

In addition, I removed that line and put it in its own file,
/etc/cron.daily/prunetmp.cron.  I actually did the same with
everything else (well, I don't do the log pruning) so it uses the
consistent run-parts method.
