go - Go 中项目的 Ebuild 示例

Question

我打算为一个用 Go 编写的项目创建一个 Gentoo ebuild，我想知道以前是否有人这样做过。

由于与其他编程语言的项目相比，从源代码构建和安装 Go 项目似乎有很大不同，因此与现有的 ebuild 进行比较以找出最佳实践对我来说很有用。

但是，在当前的 portage 树中我找不到任何依赖于“dev-lang/go”的包。是否有这样的 ebuild，也许在覆盖层中？

go-overlay怎么样？寻找例如 ebuilds？他们编写了一个特殊的 ebuild 类，用于在几行内构建 Go 应用程序和库。让我用他们的dev-util/flint-0.0.4以 ebuild 为例(所有评论都是我的):
