The dsniff package is all sorts of broken when it comes to deps; I'm not even sure what I'm missing but at least two of the binaries don't work at all.

Steps to reproduce:
dmcgee@galway ~
$ dsniff
dsniff: error while loading shared libraries: libnids.so.1.23: cannot open shared object file: No such file or directory

dmcgee@galway ~
$ tcpkill
tcpkill: error while loading shared libraries: libnet.so.1: cannot open shared object file: No such file or directory

dmcgee@galway ~
