Hi, 

   I have updated my netbsd sources tree to netbsd-4, and try to update my existing netbsd to netbsd-4 branch.
When I use build.sh to building distribution by "#./build.sh -O ../obj -T ../tools distribution" , I encounter 
the following error message:


#   install  /usr/src/../obj/destdir.i386/etc/master.passwd

I run netbsd on Thinkpad T21, Can anyone help me to resolve this problem? 
Thanks.
