You are right. The problem was the conflict with the old jack libraries
But .waf install with ldconfig did not help.
I solved this problem after building the rpm package
jack-audio-connection-kit for my operating system with profiling enabled and
updating the installed jack-audio-connection-kit with the new one.
Now I can see the message
'Engine profiling activated, beware 783 MBytes are needed to record
profiling points...'
