Question

OS X 10.7.5

我需要libjpeg v8的通用变体（jpeg @ 8d_0 + universal），但MacPorts似乎坚持认为如果我要使用通用变体，它必须是最新版本（jpeg @ 9_1 + universal）

我查看了MacPorts文档和其他资源，我找到了如何安装旧版本以及如何安装通用版本的说明，但没有解释为什么MacPorts忽略我请求的版本号在寻找通用版本时。

这就是我做了什么，发生了什么：

$ port installed jpeg
Warning: port definitions are more than two weeks old, consider using selfupdate
The following ports are currently installed:
  jpeg @8c_0
  jpeg @8d_0 (active)
  jpeg @9_1

$ sudo port install jpeg @8d_0 +universal

$ port installed jpeg
Warning: port definitions are more than two weeks old, consider using selfupdate
The following ports are currently installed:
  jpeg @8c_0
  jpeg @8d_0
  jpeg @9_1
  jpeg @9_1+universal (active)

如果不清楚，所需的最终状态是：

jpeg @8c_0
jpeg @8d_0+universal (active)
jpeg @9_1

我首先尝试卸载所有已安装的jpeg版本，然后重新尝试安装jpeg @ 8d_0 + universal，但这没有效果 - MacPorts刚刚获取并安装了jpeg @ 9_1 + universal。我试过了

sudo port install jpeg @8d_0 +universal

和

sudo port install jpeg @8d_0+universal

但也有同样的行为。

有关如何实现这一目标的任何建议？谢谢！

如何安装过时版本的端口文件的通用变体？
