Looks like that driver should depend on and #include <linux/ 
videodev2.h>, rather than <linux/videodev.h>.  I've made this change  
in CVS.  Somebody let me know if that's not the right fix (I'm not  
very familiar with V4L or V4L2).

A quick workaround is to disable the camerauvc driver, e.g.:

$ ./configure --disable-camerauvc
$ make
