Hi Graham, Hi Dane, thank you very much for your hints. At least I can render an image now, I did like here: http://wiki.openstreetmap.org/wiki/Mapnik
I don`t get any error messages any more, but the image (it`s my hometown-city) is completely blue, no streets or so at all. I will get a bit deeper into that.
