As the release notes indicate, this option is no longer needed or supported. But \
including it on the configure invocation won't be a problem either -- you'll just get \
a warning about an unsupported option.

As the release notes state, operf requires a kernel version of 2.6.31 or greater.  So \
if you're running on an older kernel, that would be one reason why operf was not \
built.  But building operf also requires kernel headers.  If you don't have them \
installed, the configure would finish with the following message:

   Warning: perf_event.h not found.  Please install the kernel headers package if you
            want non-root support built into OProfile.
