So the postflight script failed because it couldn't connect to the  
rsync server. Doesn't matter why it happened (whether our rsync  
server was down (which it wasn't) or whether the user's firewall  
prevented the connection); we should ensure that any inability to  
connect to the rsync server does not cause the postflight script to  
fail like that. Best thing would be if we could pop up a friendly  
message to the user that they need to update their installation  
themselves, but it might also be ok to just silently fail. In any  
event, the installation in the Installer should complete.
