I checked the installed versions of videodev and gspca and both are
the same versions as the versions in the build directories, so they
installed fine. I also checked the depends for videodev, v4l2-common
and v4l1-compat, and those were also the correct versions.
I double checked to make sure there weren't any modules left over in
other directories in /lib/modules/`uname -r` and didn't find any.
Since the machine in question also has a PCI video4linux device in it,
the drivers for that card already load the videodev modules.
