Apt-get install lokkit will pull in gnome-lokkit, which on a minimal Xubuntu system will pull in all the missing gnome libs, evolution-data-server etc., that a full gnome desktop would need. On 8.04 lokkit, IIRC, is roughly a 500KB install.

Which shows I have nothing stopped:-

    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination         

    Chain FORWARD (policy ACCEPT)
    target     prot opt source               destination         

    Chain OUTPUT (policy ACCEPT)
    target     prot opt source               destination
