We discussed this yesterday a bit and I think we need the libv4l port to depend on the webcamd port's patch target to get its Linux headers, that way the _IOWR etc fixes are included (of which we discovered two new ones for ca.h today btw), and the generated headers match what webcamd supports. Oh and the sed -i target needs to be changed into sed -i.bak to work with BSD sed. Thanx, :) Juergen
