compiling new ntp failed for me

[Kurt Schreiner <ks%ub.uni-mainz.de@localhost>]

Hi,

with -current source update half an hour or so ago build.sh ... distribution
fails compiling ntpd/ntpd.o:

    compile  ntpd/ntpd.o
/u/NetBSD/src/external/bsd/ntp/dist/ntpd/ntpd.c:136:20: error: dns_sd.h: No 
such file or directory

[...some failing declarations etc...]

*** Failed target:  ntpd.o

Where should "dns_sd.h" come from? I can find only this one:
.../src/external/apache2/mDNSResponder/dist/mDNSShared/dns_sd.h
which isn't used as MKMDNS=no in /etc/mk.conf...
