"apt-get source netkit-telnet" got netkit-telnet_0.17-22.  I execute
"debuild".  Then I run dpkg-shlibdeps in dpkg-dev 1.10.21:

gotom@moog:~/debian/sample/netkit-telnet/netkit-telnet-0.17> dpkg-shlibdeps debian/tmp/usr/bin/telnet.netkit
gotom@moog:~/debian/sample/netkit-telnet/netkit-telnet-0.17> cat debian/substvars 
shlibs:Depends=libc6 (>= 2.3.2.ds1-4), libgcc1 (>= 1:3.3.3-1), libncurses5 (>= 5.4-1), libstdc++5 (>= 1:3.3.3-1)
