cedet的奇怪問題

easior lars

Gentoo中的emacs工具菜單上的選項
Project Support (EDE)
Sources Code Parsers (Semantic)
無法自由選擇，一點擊前面的框，就會報錯：

Autoloading failed to define function semantic-mode

以前fedora中或者Windows中emacs均沒有出現過。

實際上，在emacs啟動之初，便有警告：

Warning: cedet-called-interactively-p called with 0 arguments, but requires 1

請問這是怎麼回事？
