按照 Ruby-China wiki《如何快速正确的安装 Ruby, Rails 运行环境》上的步骤用 rvm 安装 ruby

MacOS 10.10.1 Xcode 6.1 Homebrew: 0.9.5 Rvm: rvm 1.26.3 (latest) by Wayne E. Seguin [email protected], Michal Papis [email protected] [https://rvm.io/]

步骤 1: rvm install 2.1.5 输出如下信息： Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.10/x86_64/ruby-2.1.5. Continuing with compilation.

根据上面日志看，rvm 在开始下载 autoconf,automake,libtool 时都有出错，但进行了重试后成功了， 但是到了下载 pkg-config 时彻底失败了。

在网上找了半天也没找到解决方法，后来想用 rvm 安装其它 ruby 版本或者使用 rbenv，但是这个问题毕竟还是没搞清楚，不想放弃，望各位大神指点啊！
