为什么使用MacPorts构建ocaml bin保护失败？

我正在尝试使用真实世界的Ocaml学习

Ocaml

。我使用MacPorts安装了

ocaml

。现在，我正在尝试安装

ocaml核心扩展版
：

$ sudo port install ocaml-core-extended

但在安装依赖项ocaml bin prot时失败：

以下是构建日志中的相关部分：

$ocaml-版本
OCaml顶级，版本4.01.0
$cpp--版本
苹果LLVM版本5.0（clang-500.2.79）（基于LLVM 3.3svn）
目标：x86_64-apple-darwin13.0.0
线程模型：posix核心库的版本是什么？看起来库没有针对OCaml 4.01进行更新，可能是端口太旧了，还没有赶上进度。
我假设我遇到的具体问题更多地与向Mavericks的过渡有关

同时，我决定安装，一切都很顺利

我能够按照。
