In the end, your suggestion was too good to ignore.  I wiped out my  
changes of yesterday,
and implemented your proposal - actually a simplification/improvement  
of it. :-)

The new system allows people building from source to completely  
customize where they
want each package to go by default.

You just need to copy the new file installation-domains.conf from core/ 
make to the same
directory where your GNUstep.conf is (usually /etc/GNUstep/), then  
edit it to suit your
installation domain "needs", listing which packages you want in which  
installation
domain by default.

That's it. :-)

This new configuration file is optional and is read if it exists and  
ignored otherwise.  It is
not installed by default by gnustep-make which means the default  
behaviour is to
install everything into Local.  Another advantage of gnustep-make not  
installing it
is that once you create your own /etc/GNUstep/installation- 
domains.conf file,
it will never be overwritten or modified by gnustep-make, so it will  
be there forever
and used forever.

For all this to work well, though, all GNUstep software needs to  
always define the
PACKAGE_NAME in GNUmakefiles, as in

 PACKAGE_NAME = gnustep-base

and that needs to happen in all the GNUmakefiles.  Otherwise gnustep- 
make can't know
what it is currently installing, so it can't choose the correct  
default installation domain. :-(

I'll start updating the core packages to have PACKAGE_NAME everywhere.

Thanks
