我正在尝试在我的 gentoo 服务器上安装 python 2.7，但不知何故它已经不再安装。
eselect python list
Available Python interpreters:
[1] python3.3 *
如果我尝试以类似的方式出现它，emerge -a python:2.7它会失败并出现以下错误：
* ERROR: dev-lang/python-2.7.6::gentoo failed (install phase):
* emake failed

各种消息来源都提到了该库的问题readline，因此我按照其他人的建议屏蔽了最新的错误版本这论坛帖子。
Installed versions: 6.2_p1(02:03:23 PM 06/15/2014)
现在是最新安装的版本，应该不包含该错误。
不幸的是问题仍然存在。
我上传了完整的构建日志：https://gist.github.com/anonymous/67c66e859b6625020493
知道那里出了什么问题吗？
谢谢你！
