Subject: configure error message for missing libpfm is not informative enough
Date: Wed Oct 9 14:27:54 2013 -0500

configure error message for missing libpfm is not informative enough
    
    On the ppc64 architecture, the libpfm library is used to get perf_events
    encodings for events, so the configure script checks for the availability
    of that library when building for ppc64. If the library is missing, the
    configure error message is:
    
      checking for perfmon/pfmlib.h... no
      configure: error: pfmlib.h not found; usually provided in papi devel package
    
    However, some newer distros (like Fedora 19) are now delivering separate
    packages for libpfm and papi, instead of bundling them together. The patch
    provided herein changes the configure message to reflect that change in
    packaging.
