10-CURRENT clock_getcpuclockid() usage

clock_getcpuclockid() was added a few weeks ago according to the man page and
I'm seeing this error  while building the port net/freeswith-core-devel.

The function is used in the Sofia-sip stack, courtesy Nokia Research Center,
incorporated into FreeSWITCH.

The build system tests for the presence of clock_getcpuclockid() and finds it
but in the error messages 'clock_getcpuclockid2' is mentioned.

Any thoughts on the clock_getcpuclockid() usage would be very greatly
appreciated.
