Howdy!

I am having trouble building Pktgen-DPDK from Github on Ubuntu 14.04. Is
this supported? If so, would anybody tell me how to get the build working?

I have tried to be faithful to the instructions in README.md and I have
tested with both master and the latest release tag (pktgen-2.7.1).

The compiler output is pasted below and also in this Gist:
https://gist.github.com/lukego/bc8f7ef97ad0110c60e1

Any ideas appreciated :).
