If you want to build with png installed in /usr/pkg, you can copy 
xc/programs/Xserver/hw/xfree86/etc/bindist/NetBSD-ix86/host.def to
xc/config/cf/host.def before starting (or merge the defines there with
your own favorite host.def file)

This is how the NetBSD 1.6 binary distribution on ftp.xfree86.org was
built.
