KML Donkey

Hy guys Im having problems with the configuration file on this one. every time Y type "sh configure --prefix=/usr" I get this out put:
checking for KDE... configure: error:
in the prefix, you've chosen, are no KDE headers installed. This will fail.
So, check this please and use another prefix!

I alredy chek the prefix using "kde-config --prefix" and the system says its on "/usr"

Im running Knoppix 3.4 on my box so I have KDE 3.2. I dont know what else to do. If anyone know what to do let me know.
Thanks

I think you need the package kdelibs4-dev to get kde headers.

ok I install the package . but now I get this other out putt:
checking if UIC has KDE plugins available... no
configure: error: you need to install kdelibs first.

When I see this I run Synaptic and install the kdelibs-dev package. but Im Still getting hte out put.
