title: how do you build DTrace on Mac OS X?
body: <p>I'm trying to build the dtrace target in the Xcode project using the
  advice here:</p>
  
  <p><a href="http://osx86.boeaja.info/2009/10/building-xnu-kernel-on-snow-leopard/" rel="nofollow noreferrer">http://osx86.boeaja.info/2009/10/building-xnu-kernel-on-snow-leopard/</a></p>
  
  <p>But I get:
  libproc.m:24:49: error: CoreSymbolication/CoreSymbolication.h: No such
  file or directory</p>
  
  <p>I realize CoreSymbolication is a private framework, but Apple must
  make this header available somewhere in order for me to build dtrace,
  right? Can someone point me to the necessary files to build dtrace?</p>
