[cctalk] DECnet 5.4 install media

I am playing around with VMS 5.4 on a simulated microvax 3100 and want to get decnet running. The install media I have found is for decnet 4.0 end-node but it doesn't install. Vmsinstal complains about symbols not being defined and I am guessing I have the wrong version for VMS 5.4. Does anyone know of a decnet version that will work on VMS 5.4? I can't seem to find one. Thanks, - Peter
