After the KDE 4.1.0 import the team found time to make
KDE 3.5.9 ready for the Ports tree.

KDE 3.5.9 was released six months ago and 3.5.10 is
coming soon. We are not sure we have time to get 3.5.10
for FreeBSD 7.1/6.4 release, but we would have minimum
3.5.9 for those people who prefer to stay with KDE3.

You can see the Commit mail here.
