The reason you see this is tied up with the following:

>I don't have an ethernet interface.

So you didn't install the bnet code into the kernel, so there is no socket 
stuff, so all of the SunRPC services fail immediately. 

Shutdown is trying to warn everyone on your machine that there is going to be 
a shutdown, and using the SunRPC-based "rwall" program to do it. This is 
essentially harmless, though you might well find it useful to install the bnet 
software anyway (even if you haven't got an ethernet card).
