I could very well be out to lunch. But rsync to -current, then cvs co of src 
tree followed by a:

./build.sh -O /usr/current-objs -T /usr/current-tools -D /usr/current-build -U 
distribution

... fails with the following:

dependall ===> rescue
rm -f rescue.conf rescue.conf.tmp
TARGETDIR=/usr/current-build/rescue LDD_CMD=ldd_elf NETBSDSRCDIR=/usr/src

Run "make -f rescue.mk objs exe" to build crunched binary.

... etc ...

Any hints would be most gratefully appreciated on building -current. I don't 
know anything about the rescue crunchgen process. Maybe a pointer? I'm in the 
midst of reading the awk script but I'm not sure it'll shed any light on my 
stress-addled brain. (Stressed because of other reasons. This is my 
relaxation. :-)

Thanks!
