为什么我得到 Dependency 'p5.12-xml-parser' not found 错误？

Question

我正在尝试通过 MacPorts 安装 digikam（可惜没有 HomeBrew），但我不断收到以下错误：

Error: Dependency 'p5.12-xml-parser' not found.
Error: Status 1 encountered during processing.

我想也许我需要更新 MacPorts，所以我这样做了 (selfupdate)。然后我还尝试upgrade outdated for MacPorts，我得到另一个与 Perl5 相关的错误：

Warning: No port p5.12-locale-gettext found in the index.
--->  Computing dependencies for help2man
Error: Dependency 'p5.12-locale-gettext' not found.
Error: Unable to upgrade port: 1

我不确定为什么会这样。我用perl -v 检查了 perl，它告诉我我有 perl 5，版本 12，颠覆 3。

在进行搜索时，我看到许多人也因为某些“缺少”Perl 依赖项而在通过 MacPorts 安装某些东西时遇到了问题。不过，似乎没有任何标准解决方案。任何想法这里发生了什么以及如何解决它？

在自我更新 macports 后，我在更新我的端口安装程序时遇到了同样的问题。诀窍是再次运行 selfupdate 第二次，以便端口将获得新的源列表。

由于某种原因，这不是端口自我更新的一部分。

$ sudo port upgrade outdated

Warning: No port p5.12-getopt-long found in the index.
Warning: No port p5.12-pathtools found in the index.
