I'm trying this:

wiz@yt:/usr/src/external/bsd/nsd> USETOOLS=no make

and get
...
all ===> lib/libnsd
all ===> lib/libxfrd
all ===> sbin
all ===> sbin/nsd
make[2]: don't know how to make /disk/6/archive/foreign/src/external/bsd/libevent/lib/libevent/libevent.a. Stop

I want the build to use /usr/lib/libevent.a instead.

I guess this is

./Makefile.inc:DPLIBS+= event ${NETBSDSRCDIR}/external/bsd/libevent/lib/libevent

so perhaps what you're talking about?

What do I have to set? Do I have to do this for every library
separately?
