I just hit the problem at the second system. It would ber really good, if guvcview-2.0.1 would find its way into the portage tree.
I am seeing the same problem as well.
Versions before 2.0.1 are buggy and won't work with kernel >= 3.16: http://www.mail-archive.com/linux-media@vger.kernel.org/msg80144.html Please stabilize >=2.0.1. Thanks.
2.0.3 in the tree (please use a separate bug for the stabilization of the concrete version that should be used)
