I believe you are using rpm to install
(If not then neglect the remainder)
Download source from:
http://download.berlios.de/dcgui/dc-0.3.7.tar.bz2
Then extract it to a directory.
(The rest is on konsole)
Navigate to the directory. There will be two directories: dclib , valknut
cd dclib
./configure
make
su make install
cd ../valknut
./configure
make
su make install
I also use valknut a lot and valknut has never given me a problem, infact it is much much better than older dcgui-qt (0.2.2) . Any problems can come in ./configure stage only.
