Found this quote:

     MacOS X Panther has a lousy getnameinfo() implementation that 
doesn't fill
the buffer when no DNS entry is found for a host and a numerical result 
wasn't
explicitely asked. As a result, Pure-FTPd didn't even start on Panther 
(saying
"bad IP address") . We now check for EAI_NONAME if available and we 
retry with
NI_NUMERICHOST if this is what getnameinfo() returns. Thanks to Yann 
Bizeul
for his valuable help on this issue.

Will research it more and see if I can come up with a patch (I am NOT 
good at C!)
