In order to achieve this, while still keeping the document readable, the chapter on system requirements has been moved to instead be a section within the chapter on compiling the DPDK outside of the ports collection. This move is necessary, since it covered a lot of detail on installing other ports required to build DPDK. These steps are not needed when installing DPDK itself from ports.
