我正在尝试将appledoc用于我的一个项目。我下载了项目，在 Xcode 中构建它，并将appledoc二进制文件复制到~/bin. 尝试运行二进制文件会出现此错误：
appledoc version: 2.1 (build 858)
!> dyld: Library not loaded: @rpath/DVTFoundation.framework/Versions/A/DVTFoundation
!> Referenced from: /usr/bin/xcrun
!> Reason: image not found
docsetutil failed to index the documentation set, continuing with what was indexed...
这就是全部的输出。我做了一堆谷歌搜索，并没有真正找到任何东西；我最终删除了 Xcode（版本 4.6.3，来自 Mac App Store）并重新安装。我重建appledoc并再次尝试，但我得到了同样的错误。
我认为问题可能是我还安装了 Xcode 5 开发人员预览版，所以我想我会用xcode-select它来确保我的构建设置是健全的。但是运行xcode-select -print-path给了我一个类似的错误：
dyld: Library not loaded: @rpath/DVTFoundation.framework/Versions/A/DVTFoundation
Referenced from: /usr/bin/xcode-select
Reason: image not found
Trace/BPT trap
我也尝试过appledoc使用 Xcode 5 进行构建，结果相同。知道这里可能有什么问题吗？
编辑：这是输出otool -L ~/bin/appledoc：
