I do not seem able to compile a GENERIC kernel without changes.
I pulled down sysrc.tgz from 
ftp.netbsd.org/pub/NetBSD/NetBSD-1.5/source/sets and unpacked it to 
root.  First I tried building a custom kernel and recieved errors so 
decided to build a GENERIC. I can run config GENERIC and it exits 
cleanly. When doing a make depend I get the following results:

depend ===> stand/biosboot

I have tried downloading sysrc.tgz again and keeping the permisions with 
'tar zxpvf' and still no 'make depend'. TIA.
