I like it, but I'm getting following error:

  $ make 
      ...
      AR libperf.a
  ar: util/rbtree.o: No such file or directory
  make: *** [libperf.a] Error 1
  $

probably because rbtree object is based in kernel lib


Also this patch collides with your previous:
  perf tools: Separate out GTK codes to libperf-gtk.so

which I needed to revert first to get this one applied.
