Install pyhash on Mac

July 02, 2012

由于工作开发环境的依赖，不得已弄了Mac上安装pyhash。

install boost http://www.boost.org/ currently 1.49.0 follow manual http://www.boost.org/doc/libs/1_49_0/more/getting_started/unix-variants.html/ notice
```
./bootstrap.sh --prefix=path/to/installation/prefix
./b2 install --prefix=path/to/installation/prefix
```
record the prefix

从 http://code.google.com/p/pyfasthash/downloads/list 下载解压源代码包后，尝试python setup.py install，如果有以下报错，则继续执行第三步：

In file included from src/Hash.cpp:1:
src/Hash.h:12:28: error: boost/python.hpp: No such file or directory
src/Hash.h:13:41: error: boost/python/raw_function.hpp: No such file or directory
In file included from src/Hash.cpp:1:

修改setup.py 在include_dirs和library_dirs的声明之后添加：

include_dirs += [
    'path/to/installation/prefix/include',
    ]
library_dirs += [
     'path/to/installation/prefix/lib',
    ]

之后再执行。
