Given your explanation, I indeed I compiled with gnu-gnu-gnu, since I 
just didn't gave any options and that is what gnustep-make always 
selected, now when I upgraded libobjc2 packages from pkg, it broke. From 
what you tell me it is not a "bug" that can be fixed, but a hack that no 
longer works :)

I reconfigured with explicit --with-library-combo=ng-gnu-gnu and it 
works again.

So, essentially, one either knows that it has to be configured that way 
or our configure should be "smart" and it should enable ng-gnu-gnu from 
a certain libobjc release onwards?
