Explaining requested decisions:

For sys-auth/polkit-kde-agent:4::(install_to_slash):
    The following constraints were in action:
      * !?sys-auth/polkit-kde-agent:4, use existing if possible, installing to / (nothing is fine too)
        Because of dependent upon dev-qt/qtgui-4.8.4-r1:4::installed (DEPEND)
        Because of dependent upon dev-qt/qtgui-4.8.4-r1:4::installed (RDEPEND)
      * >=sys-auth/polkit-kde-agent-0.99, use existing if same, installing to /
        Because of >=sys-auth/polkit-kde-agent-0.99 from kde-base/kdelibs-4.11.2-r1:4::gentoo, key 'Post dependencies', labelled 'PDEPEND', conditions 'policykit?'
      * sys-auth/polkit-kde-agent, use existing if same, installing to /
        Because of sys-auth/polkit-kde-agent from sys-auth/polkit-0.112:0::installed, key 'Post dependencies', labelled 'PDEPEND'
