Ouch - you've now got version mismatch, where you didn't completely
uninstall the distro version, and your self-built version is installed
in locations that pick up the distro version.  Did you use the right
configure flags?

Ah, apt - are you on debian or ubuntu?  I don't know as much about the
versions that those distros are using (I'm personally using Fedora 16,
along with the fedora-virt-preview repo, which gives 0.9.10 pre-built).

There might be someone already shipping a pre-built 0.9.10 apt, but I
wouldn't know where to tell you to look, so building from source is the
other alternative.  If you build from libvirt.git, you can use
'./autobuild.sh --system' to help set the ./configure options that match
with the typical installation directories for at least Fedora, but
again, I don't know how that fares with the debian installation layout
(and patches are welcome to autobuild.sh for anyone that wants to use it
on a debian layout).
