the old method at bind was:

build() {
	cd $startdir/src/$pkgname-$pkgver
	./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
		    --with-libtool --enable-shared --disable-threads

	make || return 1

	make DESTDIR=$startdir/pkg install
	install -D -m644 $startdir/caching-example/named.conf \
		$startdir/pkg/etc/named.conf
	install -D -m644 $startdir/caching-example/named.local \
		$startdir/pkg/var/named/caching-example/named.local
	install -D -m644 $startdir/caching-example/localhost.zone \
		$startdir/pkg/var/named/caching-example/localhost.zone
	install -D -m644 $startdir/caching-example/named.ca \
		$startdir/pkg/var/named/caching-example/named.ca

	install -D -m644 $startdir/src/bind $startdir/pkg/etc/logrotate.d/bind
	mkdir -p $startdir/pkg/etc/rc.d/rc.messages
	install -m755 $startdir/rc.$pkgname $startdir/pkg/etc/rc.d/rc.$pkgname
	install -m644 $startdir/messages/$pkgname.* \
		$startdir/pkg/etc/rc.d/rc.messages
}

the new method:
build()
{
        Fbuild --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
                --with-libtool --enable-shared --disable-threads

        Frcd
        Ffile ../caching-example/named.conf /etc/named.conf
        Ffile ../caching-example/named.local \
                /var/named/caching-example/named.local
        Ffile ../caching-example/localhost.zone \
                /var/named/caching-example/localhost.zone
        Ffile ../caching-example/named.ca /var/named/caching-example/named.ca
        Ffile bind /etc/logrotate.d/bind
}

this includes automatically patching, using DESTDIR or prefix (detects wich is corrent), etc
