        Spice-Gtk 0.6
        ==============

        prefix: /usr
        c compiler: gcc -std=gnu99
        c++ compiler: g++

        Coroutine: ucontext
        Audio: pulse
        Target:
        SASL support: yes
        Gtk: 2.0

        Now type 'make' to build spice-gtk

make
checkinstall --install=no
dpkg -i --force-overwrite ./spice-gtk_0.6-1_amd64.deb

Libraries and binaries been overwritten are exactly the same as before.
Spice session via Virt-Manager ( video "qxl") is manageable via keyboard
before logging in (F14,Natty VM's). Mouse pointer appears and works stable
during all the time after login.
