This package is now available from devel/papi in the FreeBSD ports system.

Objective

The main objective of this project is to bring a functional version of PAPI (Performance Application Programming Interface - see http://icl.cs.utk.edu/papi for further details) to FreeBSD (http://www.freebsd.org) using hwpmc(4) kernel driver and the pmc(3) library developed by Joseph Koshy (see http://wiki.freebsd.org/PmcTools).

About PAPI

PAPI aims to provide the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. PAPI enables software engineers to see, in near real time, the relation between software performance and processor events.
