Not the with standard mathopd startup file in ports.  More likely,
you have "daemon" in your mathopd configfile.  For example, I have:

  gw% egrep 'User|Root' mathopd.conf
  User mathopd
  StayRoot Off

Well, it probably doesn't have permission...  Once you figure out who
mathopd is really running as, you should be able to figure this one
out too.  For example:

  gw% ps -axw -opid,uid,ruid,rgid,command | grep mathopd
  266  1000  1000  1000 /usr/local/sbin/mathopd

If all else fails, use "truss" or "ktrace".

Umask 027?  (I think that is configurable in mathopd.conf as well.)
