Hi,

I encountered a problem with Network.Socket in MacOS 10.5
Here is the code that I am testing,

-----------------------------------------
-----------------------------------------
module Main where

import qualified Network.Socket as Socket

main :: IO ()
main =
    do { (hostname, _) <- Socket.getNameInfo [] True False (Socket.SockAddrUnix "localhost")
       -- (hostname, _) <- Socket.getNameInfo [] True False (Socket.SockAddrInet 9000 (127 + 0 * 256 + 0 * 256^2 + 1 * 256^3))
       ; putStrLn (show hostname)
       }

Running the above code yields the following error
ghc --make -O2 TestSocket.hs
[1 of 1] Compiling Main             ( TestSocket.hs, TestSocket.o )
Linking TestSocket ...
$ ./TestSocket
TestSocket: getNameInfo: does not exist (ai_family not supported)

If I switch to SockAddrInet instead, the error is gone.

I am using GHC 6.10.3 and Network 2.2.1

Regards,
Kenny
