Your nameserver is broken. The three calls in the test script are
hostname = socket.gethostname()
ip = socket.gethostbyname(hostname)
hname, aliases, ipaddrs = socket.gethostbyaddr(ip)
and only the final one, which does the reverse lookup on your IP address,
apparently fails. The various RFC standards specify that for each IP address
the reverse mapping should always work.
As an aside, you'll also have trouble accessing ftp.cwi.nl to load a new
MacPython (as that machine uses reverse mapping as part of its anti-abuse

Yes, that's fine. Look at the xx module for an example project and such.
Hmm, I do seem to remember that something reasonably serious was fixed in this
area, so maybe you should try MacPython 1.6alfa, from

You probably won't need CWGUSI, you'll just need to remove it from the access
path of your module project (it was there inadvertantly). Unless you use
socket(), select(), stat() or another unix-compatible I/O call from within
your extension module.
