...done "make includes" and build and booted a new kernel.
with "make build" all is well 'till:

===> libwrap

Stop.

is this some side-effect from NOT beginning with a fresh /usr/src tree?
(just done "make build" in the same tree where another "make build" went
flowlessly last friday)

this is on my ss5, btw...
