1. Make sure you are running a very current /current.
   /usr/src/sys/compat/linux/arch/i386/linux_machdep.c should be:
   $NetBSD: linux_machdep.c,v 1.84 2002/12/06 03:37:19 junyoung Exp $

2. If you are using redhat's libraries, mv /emul/linux/lib/i686{,.old}
   (linux programs that use ldt's appear to be broken)

3. cd /emul/linux/usr/lib && ln -s * /emul/linux/lib

Everything should be working fine. Let me know if you see any problems.
