Thank you, Thomas!
I did it as described in https://software.intel.com/en-us/forums/topic/533393 — changed in Xcode SDK to 10.9 and removed the search path.
Caught a kernel panic in the driver then after running pcm.x for a minute.
I also had to comment out the call to freeRMID() in the PCM::cleanup() routine in cpucounters.cpp. If freeRMID() is not commented out then my Mac crashes when I hit control-C while running pcm.x. I believe that the next version of PCM will avoid calling freeRMID() on systems which don't have the RMID MSRs.
One of the Best Bandwidth Monitoring Tools which I know are
FreeMeter Bandwidth Monitor
ShaPlus Bandwidth Meter
