A few comments first:
1) Are you *sure* you want to automatically upgrade your ports this way?
While many of us do run a nightly cron job to upgrade the ports tree, INDEX
files, etc., actually upgrading the ports themselves unattended like this
may lead to trouble.
2) You could just as easily place all of these commands in a single crontab
entry, rather than invoking a script from cron.
3) This is more a matter of style and personal preference: if you setup
/etc/make.conf with proper settings for the various cvsup-related variables,
you can use "cd /usr/ports && make update" instead of manuallly invoking
cvsup. This, I think, is a much cleaner way to go about it.
4) You probably don't need *all* of those directories in your PATH.
5) "portsdb -U" is insufficient to update the files portupgrade needs to
determine which ports need upgrading. You're only updating the INDEX file,
but neglecting to update INDEX.db. Use "portsdb -Uu" instead.
6) The "-r" and "-R" switches to portupgrade are superfluous if you're using
the "-a" switch, unless you're doing a "forced" upgrade using the "-f"
switch.
7) Do you really prefer to use pre-compiled packages, rather than building
the ports from source? You're missing out on a lot of the flexibility of
the ports system by doing this.
8) If you want to get a listing of all installed ports whose versions differ
from those in the ports database, use "portversion -L '='" instead.
9) It shouldn't be necessary to explicitly pipe the output of portversion to
mail, unless you're explicitly setting MAILTO="" in your crontab to squelch
the mailing of the output of your cron jobs.

This I have no idea about. I've never seen this before. It *may* be
related to the fact that you're using packages rather than building from
source. It may have to do with the permissions/ownerships on /var/tmp
vis-a-vis the user whose cron job is being run. Another possibility is
that, with your excessively inclusive PATH, some script or program is being
invoked by portupgrade other than the one intended. Try going through your
script, doing a "which" or "whereis" on each of the commands it uses, and
don't include any other directories in the PATH than those that are
absolutely necessary. You can certainly do without "/usr/games". :-) And
"/usr/X11R6/bin" is highly unlikely to be needed either. There are probably
others as well.
