Wine我正在尝试在我的 Macbook（OS X 10.9.3）上安装。
首先，我尝试使用Homebrew列出一组依赖项的内容，然后去获取第一个。
==> Installing dependencies for wine: libtiff, gd, libgphoto2, little-cms
==> Installing wine dependency: libtiff
==> Downloading ftp://ftp.remotesensing.org/pub/libtiff/tiff-4.0.3.tar.gz
此时超时
沮丧的是，我尝试使用Macports，它同样可以解决依赖关系，获取大量依赖关系，但当达到
Attempting to fetch MesaLib-8.0.5.tar.bz2 from ftp://ftp.freedesktop.org/pub/mesa/older-versions/8.x/8.0.5/
该过程再次挂起并最终失败。
这两个文件都可以通过浏览器或使用ftp命令行下载。但是，Homebrew 似乎正在尝试使用下载。尝试使用如下方式cUrl下载它们...cUrl
curl -O ftp://ftp.remotesensing.org/pub/libtiff/tiff-4.0.3.tar.gz
超时（编辑：错误 56）
我的 cUrl 有问题吗？为什么 Homebrew 或 Macports 无法通过 ftp 下载文件？
编辑
这可能是 openSSL 的问题吗？我
OpenSSL 1.0.1g 7 Apr 2014

tcpdump尝试
curl -O --ftp-pasv ftp://ftp.remotesensing.org/pub/libtiff/tiff-4.0.3.tar.gz
抱歉，篇幅太长了，但我不知道这有多少相关性。这是在监听主机 ftp.remotesensing.org 的流量。
sudo tcpdump -nS -i en0 host ftp.remotesensing.org

尝试使用被动模式，例如--ftp-pasvcurl 选项。如果此方法有效，您也可以在 curl 的配置文件中指定此选项（$HOME/.curlrc有关详细信息，请参阅手册页）。
