 Nope, that's all there is to it.  Replace misfunctions.cpp with the link I gave above, set compiler/linker to gcc-2.95, compile, and enjoy.  Are you passing "zone" the proper arguements?  It should be something like this:
 ./zone . 123.123.123.123 7995 123.123.123.123
 
 where 123.123.123.123 would be replaced by your real IP# and 7995 is the port used by that zone server.  To run multiple zone servers just execute the same command but increment the port by 1 each time.
