I believe this thread was about the Yun image and packages that were in use before the one that was just released. If you have upgraded to the new image then run
opkg remove kmod-video-gspca-ov519
opkg remove kmod-video-gspca-core
opkg update
opkg install kmod-video-gspca-ov519
and if you have /dev/video0 then ignore the rest of this thread, you should have the modules installed for a Creative Live! VISTA VF0470.
When you use --force-depends I believe it will still show you the error even though it installed it.
Do you see kmod-video-gspca-ov519 when you run opkg list-installed?
Is there a file named /dev/video0?
Did you install the gspc-ov519 module from chef.mesh.altermundi.net, Dropbox - File Deleted - Simplify your life, or the official repository http://downloads.arduino.cc/openwrtyun/1/packages?
