problem with supfile

[Pollywog]

Someone please tell me why my supfile is not working.  I think the problem is 
the tag but I am unsure why:

*default host=cvsup2.FreeBSD.org
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=RELENG_6_2
*default delete use-rel-suffix

# If you seem to be limited by CPU rather than network or disk bandwidth, try
# commenting out the following line.  (Normally, today's CPUs are fast enough
# that you want to run compression.)
*default compress
