qmail compile problem

[Igor Gueths]

Hi all. I am currently trying to compile Qmail-1.0.3. I figured I would
switch MTA's since I am going to be running my own domain. However I am
running into a compile problem, here's the relevant part of the output.

I am not exactly sure as to what ld is looking for. Does anyone know what
ld is trying to find and can't seem to locate? Thanks!
