The server itself does not depend on inets, so that would be wrong.

Right. The plug-in dependency calculations filters out all app 
dependencies which can be loaded. More generally, the code in 
rabbit_plugins assumes that it executes on the user's rabbit runtime. 
Hence inets, kernel, stdlib, etc never feature in the dependency 
calculation in normal use.

It is not immediately clear what needs to change to make that code work 
in a different context, i.e. a release build. Over to you :)
