[erlang-questions] Met problem when using distel at emacs

[Arbow]

Hi:
    I followed this article:
http://bob.pythonmac.org/archives/2007/03/16/distel-and-erlang-mode-for-emacs-on-mac-os-x/,
installed the newest distel from svn.
    When I press (C-c C-z) start an erlang console at emacs, and press
(C-c C-d l), message console print following messages:

"DeepBlue / -27924 servname not supported for ai_socktype"

Could anyone help me, thanks:)
