As far as I can tell, there isn't a ffi library on NetBSD, at least I 
don't see on in /usr/pkgsrc.  Does it come as part of gnustep-base ?

My mistake in how I worded the above.  Here is what it says in the 
package description:

   "The runtime is modeled after the NeXT Objective C runtime. That is, 
most functions have the semantics as it is known from the NeXT.  The 
names, however, have changed.  All runtime API functions have names of 
lowercase letters and underscores as opposed to the 'traditional' mixed 
case names."

To me this means the following:

gnustep-base API           gnustep-objc API
----------------           ----------------
 GSAtomicMallocZone         gs_atomic_malloc_zone
 GSBreakTime                gs_break_time
 GSCurrentThread            gs_current_thread
 GSDebugSet                 gs_debug_set
 NSAllocateObject           ns_allocate_object
 NSCopyObject               ns_copy_object


Is my understanding correct ?  Is this what I want ?  Or should I just
install gnustep-base and gcc-objc and leave it at that (along with
gnustep-make) ?

Based on what folks have said here, I believe that as long as I have
gcc (with objc support), gnustep-make, and gnustep-base, I should be
just fine, yes ?

cheers,

p.s. This seems to be only there on NetBSD, and not on Debian.  Using
     the packing list to look for files in Debian packages turned up
     nothing.  Also, a quick look around the GNUstep download area
     doesn't mention gnustep-objc although it seems to have come from
     GNUstep FTP site, as per the NetBSD Makefile
