The port might have to refactored a little with kde4.3 anyway, since oxygen-
icons will be packaged seperately, if I am not mistaken.

Also the next version is on its way, which might bring changes.

Feel free to commit from my side!

P.S: the reason for not choosing kdesu as target dependency was its frequent 
cahnge in location...
