Portupgrade Broke?

[Bob Perry]

I run FreeBSD 4.7 RELEASE.  Just ran the portversion command for the 
first time since last Saturday and the ouptut indicated that my 
installed packages were up-to-date.  Thought it odd so I ran pkg_version 
command and picked up 9 packages in need up upgrade and several 
"orphaned" packages listed.  Is there a known problem with the 
portupgrade system or was there some warning I missed previously?

Thanks,

Bob
