Hello.
This is what happening when I try to install kde via pkg, following this guide :
http://daemon-notes.com/articles/desktop/kde

I'm using portmaster to keep my ports updated the old fashion way.
Had to build xorg and nvidia-driver the usual way "make install clean" from the portstree.
virtuoso worked with pkg install

root at ymer:/home/hasse # pkg install kde

Prior to the above, I've tried to run :

root at ymer:/home/hasse # pkg clean -a
Nothing to do.
root at ymer:/home/hasse # pkg update -f
