好的，所以为了全面披露，构建 RPM，包括软件集合并不是我的日常工作，所以如果我错过了一个明显的技巧，请道歉。
我的目标是创建一个包含一堆 python 模块的软件集合（我们自己的代码加上一些当前在主集合中不可用的依赖项）。我正在运行 RHEL 6.4。
我想采用的方法是尽可能依赖主要的python27包（python27-python-2.7.5-10.el6.x86_64，python27-python-libs-2.7.5-10.el6.x86_64 , python27-python-jinja2-2.6-10.el6.noarch 等）
因此，希望作为 python27 集合的一部分已经可用的所有内容最终都低于 /opt/rh/python27（标准），而我需要添加的所有内容都低于 /opt/myorg/mycollection，避免 /opt/ rh 用于任何非标准的东西。
对我来说似乎是正确的策略，但如果有更好的替代方法，我会很高兴听到它。我想到的一件事就是将 python27 完全打包到我们自己的集合中，但感觉不是最好的路线。
因此，在创建了元包文件（见下文）后，我遇到了以下问题：
- “/opt/rh/...”文件在构建元包时列出了两次警告。*
- (1) 波及到我基于元包构建的包。
* - 即使我在软件集合 v1.2 打包指南（“扩展 python27 和 python33 软件集合”，最初按照http://developerblog.redhat.com/2014/03/ 27/在 rhscl 顶部构建软件集合/
我怀疑问题与一些预定义的宏（scl_prefix？）有关，但我无法破解
L'il 帮助非常感谢。
