Can you give some more information on what prompts you are getting and 
your responses. It may be nothing to do with a custom datum if the 
problem is at the false northing stage... that is when details of the 
projection are being entered. Perhaps you are using a projection that 
has buggy support from g.setproj. It doesn't support interactive 
entering of all projections in PROJ and is known to have bugs in some 
that it does support (lcc comes to mind). If you know the PROJ 
parameters you can manually edit the PROJ_INFO file after setting up to 
fix it and things will work just as well.
