Here is an ebuild for the newest kcachegrind. It is marked as unstable by the developer. I fixed some bugs with the ebuild (missing RDEPENDs etc). This version features a new GUI with more features than previous versions, sadly it has also grown quite a bit.
Created attachment 15808 [details] dev-util/kcachegrind-0.4.0.ebuild
"A kde frontend for the cachegrind profiling tool, which is part of valgrind" Then you need to add valgrind to the deps?
Yes, that might be a good idea too =). >=dev-utils/valgrind-1.9.0
It depends on calltree which depends on valgrind, so a direct dependency is not necessary.
0.4.1 is now in portage.
