# trying to build a more-recent tshark only for RHEL6 than what comes stock (1.8.10 as of this writing);
# grabbed 2.6.6 source
# N.B.: Make sure you have PLENTY of disk space! my build died at least once due to space constraints!
# make sure you have software collections enabled, and install python27 from extras
# directory "build" is a sibling of wireshark-2.6.6 (sources)
