Under this git pull, I have verified building and installing dpdk on x86 
with this diff to switch to pkg-config

One uncertainty is numa,  "Requires: numa",
This requires numa.pc has to be installed, so numa only can be installed 
from source code (make install).
While apt-get install libnuma-dev does not install numa.pc, so system 
can not search numa.
So do we have to build numa from source code?

Thanks
