libdnet 2.61 (arm64 binary) in ubuntu trusty

 This package contains the libraries necessary for a functioning DECnet
 system. Most DECnet programs require these libraries to be present on
 the system. The libraries are:
 libdnet - the basic DECnet API as featured on Ultrix(R) systems
 libdnet_daemon - useful calls for writing DECnet daemons
 libdap - DAP (Data Access Protocol) C++ classes
 librms - High level library for programmatic access VMS files
                  from Linux.
 .
 To do useful work with DECnet you will also need the dnet-common
 package.
 .
 If you're looking for libdnet, the "dumb" networking library from
 libdnet.sf.net by Dug Song then you should install libdumbnet instead.
 Sorry for any confusion caused!
