Ruby 1.9.3 安装

很老的系统，用到这个，在 macos 上的安装过程

先添加一些临时的环境变量

# 这个最重要
export CFLAGS="-Wno-error=implicit-function-declaration"

# 这些是2.4以下安装时候需要添加的
export PATH="/usr/local/opt/openssl@1.0/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl@1.0/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.0/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.0/lib/pkgconfig"
