Remove update queue

[Norm]

How does one remove the update queue in fc6
I used the update software process and tried to update some 
applications.  This time it told me that it needed libetpan  so it could 
update some applications.  In the past it I removed the "trouble 
applications from the queue and found the dependency and installed it 
all worked well.  This time when I try to install  the dependency I am 
told I can not install it until I install l the very dep I am trying to 
install because the dep is need to install other applications.  At a 
guess I should be able to get things under control if I can flush the 
queue. Any suggestions as to how I can get past this circular logic loop?
