error building libpmc_events.c

Hi,

During a buildworld of head on amd64, from 332518 to 334590, the build 
stops with:

--- all_subdir_lib/libpmc ---
===> lib/libpmc (all)
--- libpmc_events.c ---
./pmu-events/jevents "x86" /home/src/lib/libpmc/pmu-events/arch 
libpmc_events.c
sh: ./pmu-events/jevents: not found
*** [libpmc_events.c] Error code 127
...

TIA

CBu
