Linux 如何正确编写Gentoo的ebuild

是否有人可以帮助为创建ebuild？这是我的工件ebuild（针对osc修改了ebuild）：

覆盖信息：

ls /usr/local/portage/dev-util/gbs/
Manifest  gbs-0.13.tar.gz  gbs-0.13_alpha.ebuild  gbs-0.13_alpha.tar.gz

cat /etc/portage/make.conf | grep DISTDIR
DISTDIR="/usr/local/portage/distfiles"

emerge -s "%@dev-util/gbs"
*  dev-util/gbs
      Latest version available: 0.13_alpha
      Latest version installed: [ Not Installed ]
      Size of files: 0 kB
      Homepage:      https://source.tizen.org/documentation/reference/git-build-system
      Description:   Command line tool for building packages for Tizen platform

当我试图编译这个ebuild（至少是解包）时，我得到了以下错误。 解包源代码的输出：

您尚未定义SRC_URI。这就是它用来下载tarball的方法。您不会将其包含在ebuild目录中。即使您事先已经下载了它，也要坚持使用/usr/portage/distfiles

此外，您的所有功能（可能除了pkg_设置，不确定）都是冗余的。默认函数将正常工作，因此请删除它们。
