Did you follow the instructions and you have made your "lldb_codesign" code signing certificate?:
svn cat http://llvm.org/svn/llvm-project/lldb/trunk/docs/code-signing.txt If you don't do this, your debugserver won't have the ability to debug anything. If you don't want to do this, you can remove the "debugserver" binary from your LLDB.framework that you built and are running with, and then we will fall back to using the one that is installed inside /Applications/Xcode.app as that one is Apple code signed.
