Once again my ignorance of all things networky bite me. Can anybody explain what this message might mean?

/usr/local/lib/ruby/1.8/net/ftp.rb:350:in `gethostbyname': getaddrinfo: No address associated with nodename (SocketError)
         from /usr/local/lib/ruby/1.8/net/ftp.rb:350:in `getaddress'
         from /usr/local/lib/ruby/1.8/net/ftp.rb:373:in `login'

Looks to me like you're trying to connect to a hostname that doesn't resolve to an actual IP address.
