upgrade of portupgrade

[n dhert]

Today, my nightly run of portsnap informed me there is un update for:
# pkg_version -vIL=
 portupgrade-2.4.9.3.2  < needs updating (index has 2.4.9.3_1,2)

Since there is no special entry in /usr/ports/UPDATING about the
portupgrade  update,
I started my weekly
# portupgrade -yaRrpb

this gives:

What's this problem with  pkgtools ???
I have a
$ ls -la /usr/ports/distfiles/pkgtools-2.4.9.3.tar.bz2
-rw-r--r--  1 root  wheel  79394 Aug 23  2011
/usr/ports/distfiles/pkgtools-2.4.9.3.tar.bz2
but no 2.4.9.3_1,2  version

And, strange: if I try
http://www.freebsd.org/ports, Search for  pkgtools in All
it finds nothing  ???  Isn't that package described ??

What's going on here and how to solve it ??
