The qperf-0.4.7-0.1. gf3f7001.tar.gz contained a packaging mistake. I have created an updated 0.2 version. I have verified that it install.pl will correctly build it in the OFED-3.5-20120816-0600 release. Please use the updated file, here on beany: /var/www/downloads/qperf/qperf-0.4.7-0.2.gf3f7001.tar.gz Thanks, Dean
