使用 macports 指定要安装的版本
我想在 mac os x leopard 上使用 macports 安装特定版本的 gdb 和 gcc，不是最后一个，而是 gdb 的 6.8。是否可以？

这是可能的。这只是复杂而乏味的。它最近在文档中列出了。
步骤
转至 macports trac 并找到您要查找的软件包为了。 这是 subversion 的链接，即我将在示例中使用的包。
单击端口文件
单击修订日志（右上角）
仔细查看修订版本，直到找到所需的版本。记住修订号。
在此示例中，我正在查找 1.7 版的 subversion。
注明修订号。您需要在该修订版中签出该子目录的版本。
然后 cd 进入该文件夹并运行安装
然后它应该被默认选中。您可以检查
It is possible. It's just convoluted and tedious. It's listed in the documentation these days.
Steps
Go to macports trac and find the package you're looking for. This is the link for subversion, which is the package I'll be using in the example.
Click the PortFile
Click Revision Log (top right)
Pour through the revisions until you find the version you're looking for. Remember the revision number.
In this example I'm looking for version 1.7 of subversion.
With that revision number noted. You need to checkout the version of that subdirectory at that revision.
Then cd into the folder and run the install
Then it should become selected by default. You can check with
当我在试图弄清楚如何下载旧版本的curl时刚刚遇到这个问题，我想我应该分享一个更新：
当前接受的答案不再对我有用。这是 MacPorts 2.2.0 的情况。我所做的如下。
我开始按照此处的说明进行操作。我最终使用了 SVN 方法，因为第一种方法不起作用。我没有意识到我错过了关键的一步。
我发现另一篇文章建议将下载的目录移动到
/private/tmp。完成此操作后，我cd进入新目录，并在sudo port install之后我能够安装旧版本。我使用的是运行 OS X 10.8 的 Mac，因此您的情况可能会有所不同。
As I just came across this question when trying to figure out how to download an older version of curl, I thought I'd share an update:
The currently accepted answer did not work for me any longer. This is with MacPorts 2.2.0. What I did was the following.
I started following the directions located here. I ended up using the SVN method, since the first method didn't work. What I didn't realize is that I was missing a critical step.
I found another post that suggested moving the downloaded directory to
/private/tmp. After doing this, Icdinto the new directory and after asudo port installI was able to install the older version.I am on a Mac running OS X 10.8, so your mileage may vary.
这篇文章很旧..但指定版本是可能的。例如，我想安装 ZeroMQ 版本 3.2.2，所以我使用：
访问 MacPorts 网站并搜索以查看他们是否有您想要的内容总是有帮助的。
This post is old.. but specifying a version is possible. For example I want to install ZeroMQ version 3.2.2 so I use:
And it always helps to goto the MacPorts website and search to see if they have what you are looking for.
据我所知，根本不可能安装除确切版本之外的其他版本，除非某个版本有特定的端口。
您唯一能做的就是从 Macports subversion 存储库中获取所需版本的端口文件。
在你的情况下，当前版本只有 gdb 7.2 可用，没有变体，也没有其他版本 - 抱歉:)
As far as I know it is not possible at all to install other versions than the exact version, unless there is a specific port for a certain version.
The only thing you could do is fetch the portfile of the desired version from the Macports subversion repository.
In your case only gdb 7.2 is available on the current version, no variants and no other versions - sorry :)
