Important: If you are compiling this on a system with both KDE 2 and KDE 3 then you must specify the base directory of KDE 3 as an argument to ./configure. For example, if you have your KDE 3 in /opt/kde3 then you'd build like so:
./configure --prefix=/opt/kde3
make
make install
If you do not do this, you may get compile errors. You should be alright if you only have KDE 3 though.
