There are probably better places to put this, but for now,
I've put a full set of binaries for the x11r6 core on:
	ftp.netbsd.org:/pub/NetBSD/arch/sun3

For your convenience, I've split it up as follows:

  -rw-r--r--  1 gwr       1978589 Jul  7 18:10 x11r6base.tar.gz
  -rw-r--r--  1 gwr        744638 Jul  7 15:34 x11r6comp.tar.gz
  -rw-r--r--  1 gwr       2521339 Jul  7 15:44 x11r6font.tar.gz

base:
	Minimal setup for run-time use (no compilation)
	binaries, shared libraries, lib/X11 stuff...

comp:
	Things you may need to compile programs, such as
	archive libraries, headers, X11/config, etc.

font:
	The base package has only lib/X11/fonts/misc
	This package contains all the other fonts:
		lib/X11/fonts/75dpi
		lib/X11/fonts/100dpi
		lib/X11/fonts/Speedo
		lib/X11/fonts/Type1
	Note that I omitted the following from fonts/misc
		gb16fs.pcf gb16st.pcf gb24st.pcf
		hanglg16.pcf hanglm16.pcf hanglm24.pcf
		jiskan16.pcf jiskan24.pcf k14.pcf
	These are huge (about a megabyte each!) so if anyone
	wants them I'll put them up as a separate tar file.

All the tar files above should be unpacked in:
/usr/X11R6

Enjoy!
