[OS X TeX] TeX Live Utility: installfont persistently listed

[Joshua Smith]

All,

When I use TeX Live Manager to update TL2010, it lists the following  
three packages with status "forcibly removed":

installfont
installfont.universal-darwin
installfont.x86_64-darwin

Once I update any other packages, tlmgr says that no updates are  
available, but these three packages remain in the main window, still  
with the status "forcibly removed."  What are these packages and why  
do they always appear?

Thanks,
Josh
