I suppose your version of GEM doesn't support cameras with video2linux2 support.

One quick thing to try would be to "aptitude install libv4l" and then preload
the compatibility library for V4L1 apps by doing:
$ export LD_PRELOAD=/usr/lib/libv4l/vl1compat.so
$ pd -lib Gem

Otherwise try to get a Gem that supports v4l2, for example by recompiling it after
installing libv4l-dev, too.
