似乎无论我做什么，我都无法让我的MacPorts连接到美国服务器。

我的sources.conf文件只包含一行：
# For proper functionality of various resources (port groups, mirror
# sites, etc.), the primary MacPorts source must always be tagged
# "[default]", even if switched from the default "rsync://" URL.
# rsync://rsync.macports.org/release/tarballs/ports.tar [default]
rsync://sea.us.rsync.macports.org/release/tarballs/ports.tar [default]
在我的macports.conf中，我有：
rsync_server sea.us.rsync.macports.org
有人有任何线索吗？
