Also, as we have recently discovered, enabling DPDK libraries 
system-wide may not be so trivial after all, and may involve running 
ldconfig and/or modifying the /etc/ld.so.conf.d/ to include the locally 
built libraries. Should we include this as well? An argument can be made 
that this is distro-specific and shouldn't be in this guide, but these 
problems happen on distros that are common enough and are explicitly 
supported by DPDK, so perhaps /some/ note on possible issues with 
library search paths should be present?
