The KDE team released KDE-4.1.2 two days later than planned.
We are in a ports slush and can’t update KDE until it’s
ended. If you can’t wait to get KDE 4.1.2, you can now
download it from our area51 repo. The full KDE changelog
can be seen here. We removed FAM support completely.
This gives a bit more speed and the program starts faster.
Thanks to Kris Moore (PC-BSD) who tested this patchset,
we also removed the KDE debug modues.

And a tweak reported by from Hannes Hauswedell.
He experience high CPU-Usage by kded4 and slowdowns
with Konqueror as Filebrowser, he recommends you
try radically lowering the DirWatch-rate of kded4
by adding the following to your
$HOME/.kde4/share/config/kdedrc:

[DirWatch]
PollInterval=60000

This is explained here.

So, if you want to get the port, please read following
instructions:

Note: you also need to first update Qt4 to
4.4.2
