Why do I have to keep doing "portsnap extract"?

Yes, I did; I followed the instructions exactly.  I ran portsnap for
the first time a couple weeks ago after which I successfully did a
bunch of portupgrades.  Then the ports tree sat there on my disk
untouched for a couple of weeks until I ran "portsnap fetch update"
today.  For some reason it insisted that I needed to run "extract"
when as far as I can tell that shouldn't have been necessary.

Is there some configuration information I should be mentioning?  I
haven't changed anything in /etc/portsnap.conf, I am using all the
defaults.
