1, Restored kamera with a WITH_GPHOTO2 knob that works like the WITH_SANE knob.
That is, it looks for gphoto2-config.
2, pkg-plist changes to go with (1).
3. Changed WITH_SANE= to WITH_SANE?= (and WITH_GPHOTO2 is the same) so that
even if the package is installed you can build kdegraphics without it by
using WITH_SANE=no and/or WITH_GPHOTO2=no.
4. No PR, just request on list and it seemed reasonable.
