errors.  However, I can't seem to install the thing.  Following the
instructions in /doc/README.install as best I can, I:

unpack the tarball
cd 0.10
make
sudo make install
modprobe -r ivtv
depmod
modprobe ivtv

Hoever, when I go and look in the message log, I see that version 0.10.1 is
still loading.  What am I doing wrong?
