caedeのインストール問題

[heavybugtracker]

さっそく回答を頂き、ありがとうございます。
httpに変えたらインストール先に進みました。　
残念なことに、別のエラーが発生してしまいました、詳細は次の通りです：

Cannot complete the install because one or more required items could not
be found.

何か、こちらでまずいことやってしまったように思いますが、手順(http://caede.curl.com/ja/gettingstarted_...ml?mode=pc)通りにやっただけなのに...

すみませんが、だれか教えて頂けますか？
