  gethostbyaddr- get network host entry by address

  Syntax
  ======

  cc . . . -lsocket

  #include  <netdb.h>

This man page tells us that we must #include <netdb.h> before using these functions and that we must be sure that our cc line links against the socket library by having a '-lsocket' at the end.

This same technique should be applied to any link error that you feel the system really does know about but you just don't know where it is.
