simple: the version of Gem you are using has been compiled without
libv4l support.
whoever built the package has either not enabled libv4l-support (there
is a new flag in Gem's configure called --without-ALL which disables
everything so you have to manually re-enable whatever you want; this is
meant for package-maintainers so they have better control about what
features the package will have) or there was no libv4l-dev installed on
the build machine.

solutions:
- build Gem yourself and make sure that you have all relevant packages
installed (in your case, don't forget libv4l-dev)
- ask the person who built your package to enable libv4l
