The gspca driver is getting built against the media drivers in your kernel
source, but the media drivers you are using are the newer ones from the
v4l-dvb Hg you installed.

What you might be able to do, is to use
make kernel-links

from v4l-dvb to copy v4l-dvb into your kernel source.  This will modify the
kernel source you have installed, so you probably should back it up first!
Now you can try to rebuild gspca against this new source.
