我有 gentoo linux，我在上面运行 gitlab 实例。我无法升级到dev-vcs/gitlab-gitaly-1.7.1当安装执行命令时
bundle install --deployment
输出为：

我尝试重新安装 bundler、升级 ruby、禁用 ipv6 路由，但都无济于事。我已验证我能够访问https://rubygems.org/使用 wget 后，我可以 ping rubygems.org。我猜想 openssl 可能存在问题。我有 dev-libs/openssl-1.0.2r 和 dev-lang/ruby-2.4.6 以及 dev-lang/ruby-2.5.5，但使用其中任何一个都不起作用。有人遇到并解决了这个问题吗？
