Many Applets in KDE Playground trunk are broken

Unfortunately many of the applets do not compile. At least not on my Kubuntu 8.04 system with KDE 4.1b2. If you want to try out a few, checkout one of these: calendar charselect darkstat embed-win keyboardLeds previewer timer toggle-compositing wifi-signal-strength.

I especially like wifi-signal-strenght: Easy but nice and rather pretty. Get it with

svn co svn://anonsvn.kde.org/home/kde/trunk/playground/base/plasma/applets/wifi-signal-strength

And compile it with:

cd wifi-signal-strength
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr/lib/kde4/
make

You may have to replace with PREFIX with the one from your distribution.
