OMPT support is currently disabled in MacPorts libomp ports (`-DLIBOMP_OMPT_SUPPORT=FALSE` is specified in the portfile), and has been so for almost 4 years. I am not aware why it is disabled. Unless a maintainer has already noticed this thread, I would suggest opening a ticket to request OMPT be enabled.
