kernel 2.6.32-71 seems to be Centos 6.0? MLNX Ofed supports 6.3-6.5 (different files to download). Please update your distribution first.
I checked again, 2.6.32-71 is the RHEL6.0 kernel- why don't you update to 2.6.32-431 (6.5) oder -504 (6.6)? Where did you get the kernel from?
try logging in as root user and do it again.. i see you are using sudo user.
