it seems like configure does not recognize that you have libv4l installed.
if you want to compile Gem with native libv4l support, make sure that
you also have the _development_ packages for libv4l installed
("libv4l-devel" or the like on rpm-based distros)
if you want to just use the LD_PRELOAD hack, then you won't see the
"video4linux2" line when starting Gem but it should work anyhow...
