没有Wget的日子是非常难过的，强大的Mac OS 下安装Wget非常简单

下载一个Wget的源码包，http://www.gnu.org/software/wget/

安装与配置

1. 首先下载一个Wget的源码包

http://www.gnu.org/software/wget/

2. 进入到解压的目录

tar zxvf wget-1.9.1.tar.gz

3. 输入：./configure

末尾几行执行结果：

...

configure: error: in `/Users/Richard/Documents/Dev/tools/wget-1.17':

configure: error: The pkg-config script could not be found or is too old.  Make sure it

is in your PATH or set the PKG_CONFIG environment variable to the full

path to pkg-config.

Alternatively, you may set the environment variables GNUTLS_CFLAGS

and GNUTLS_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.

See `config.log' for more details
