callgrind and graphviz

[Caolan McNamara <caolanm redhat com>]

The kdesdk rpm includes kcachegrind, but callgrind and graphviz are not
in FC3, callgrind is the actual calltree generating backend for
kcachegrind, while graphviz is used to draw the pretty calltree
diagrams. 

Are there existing reasons why they are not in FC ? oversights or is
there licence issues, esp with graphviz ?
