1. All three are start automatically when needed ... unless GNUstep is  
improperly installed.
2. gdnc does not require gdomap (except in the case where you are  
manually running special copies of gdnc to support notifications  
between different users/machines)

So if gdnc is trying to use gdomap, either GNUstep is oddly configured/ 
installed, or a really, really old version is being used.
In either case it makes sense to completely remove the existing  
installation, get an up to date copy, and configure/build/install in  
the standard manner.
If using a packaged version of GNUstep, it's possible that the  
packager misconfigured it (or deliberately configured it to use tcp/ip  
based distributed notifications) ... in which case the thing to do is  
contact the package provider and ask them what to do (perhaps they  
documented their changes).

Good advice for possible installation problems with gdomap, but this  
should not effect gdnc as it normally uses unix domain sockets.

gdnc does need to be able to write to the temporary directory  
(normally /tmp), but a permission problem there would be very strange.
