Curious yum problem

[Timothy Murphy]

I just installed FC-5 on a new disk,
and when I tried "yum update" it failed because, it reported,
kdebase required htdig .

On the other hand, I can update kdebase on other FC-5 systems
which I have kept up-to-date.

It doesn't particularly matter - I as able to update nearly everything
by "yum update [a-j]\*", etc,
but I am puzzled why this problem arises,
and interested to know if there is a simple way
of determining exactly what is looking for what?
(It seemed that other packages were looking for htdig.)
