Compile normally but have libv4l-dev installed before.

Personally, I use
	./configure --prefix=/usr --enable-oss --enable-v4l --disable-avc 
--disable-dc

One of my students had this too (v4l plugin not compiled), I do not 
understand why.  It seems it was solved by installing uvcvideo, but this 
is doubtful.
