debian/control file needs to look like this:
***
Source: nsd
Section: net
Priority: optional
Maintainer: Ondřej Surý <ondrej@debian.org>
Build-Depends: debhelper (>> 4.0.0), libwrap0-dev | libwrap-dev, cdbs,
bison, flex, groff, libssl-dev
Standards-Version: 3.6.1
Package: nsd
Architecture: any
Depends: ${shlibs:Depends}, ${misc:Depends}

Description: authoritative name domain server
NSD is an fast, authoritative only, high performance, simple
and open source name server.
.
The NSD was primarily developed by NLnet Labs on request from and close
cooperation with RIPE NCC, as an alternative name server software to be
run on the root name server RIPE NCC operates.
***
So you are missing source section in control file and that is the
problem.
Ondrej.
