yum won't remove a package that it lists as present

[Chris G]

Why won't yum remove the older qt.x86_64?  See below:-

    home# yum list qt
    Loading "installonlyn" plugin
    Installed Packages
    qt.x86_64                                1:3.3.8-4.fc7 installed       
    qt.x86_64                                1:3.3.8-7.fc7 installed       
    Available Packages
    qt.i386                                  1:3.3.8-7.fc7 updates         
    home# yum remove qt-3.3.8-4.x86_64
    Loading "installonlyn" plugin
    Setting up Remove Process
