Description of problem:
sane-v4l is no longer being built in current sane-backends packages because in current releases of sane-backends, it requires libv4l. This means webcams cannot be used as image acquisition devices anymore. Please add:
Version-Release number of selected component (if applicable):
(Those are the current releases in updates, they're definitely all affected, I haven't checked older packages as they're obsolete anyway.)
Steps to Reproduce:
Just try firing up xsane with a webcam plugged in, or even just inspect the package and/or the build log.
sane-v4l backend missing.
sane-v4l backend available.
The build.log says:
checking for LIBV4L... no
*** v4l backend requires v4l libraries - disabling
libv4l is small, but if the dependency is unwanted in the main package anyway, a subpackage like for the gphoto2 backend would be possible. (But I'm personally in favor of things working out of the box.)

I agree that libv4l is not much of an additional burden (it's small and doesn't pull in other requirements), so I'll put in the v4l backend in the main package.
But (and that's referring to your comment in the other bug ;-): I'm not a friend of requiring other packages just because it makes some things working "out of the box" in some situations -- that's what comps is for. In that other case, requiring libsane-hpaio it would pull in cups, dbus, net-snmp libs which is not always desirable (since it would use much more space than, say, libv4l).
