I've tracked this problem, too.

This problem is in changes in pax.

1. /usr/src/bin/pax/tar.c uses gid_from_group() and uid_from_user() in
   /usr/src/lib/libc/gen/pwcache.c.
2. These function uses setgroupent() and setpassent() in
   /usr/src/lib/gen/getgrent.c and /usr/src/lib/gen/getpwent.c.
3. And contain reference to YP fuctions which don't exist in libhack.o
   but yplib.o in libc.a.

I analyzed and tired now...
