"does not recognize connectionForProxy"

Hi.

I'm working on porting GNUstep to the OpenBSD OS.
So far, everything compiles and installs fine under x86 and amd64 but 
I'm having a problem starting GNUstep applications (addresses, 
GNUMail...) under powerpc.
Each time I start an app ("APPname" or "openapp APPname") I get the
following error:

NSInvalidArgumentException: GDNCServer(instance) does not recognize 
connectionForProxy

Note that GNUstep.sh has been sourced and gdomap, gdnc and gpbs have 
been
started.
Version info:
gnustep-back-0.12.0
gnustep-base-1.14.0
gnustep-gui-0.12.0
gnustep-make-2.0.1

Any idea what's going on here?
Thanks.
