I've added PLCrashReporter to my OS X application and am successfully saving the crash dumps to a server. However, plcrashutil does not appear to symbolicate even with the .app and .dSYM in the same directory as both plcrashutil and the crash file.
I also tried following the instructions in TN 2123 for using gdb to get the address and it fails to give a source line for the symbols reported in the crash file.
