Mac OS XにRubyをインストールしたら失敗した話し #Ruby

↑辺りを参照しながらインストールしたところ、RVMを使ってRubyをインストールするところでエラーが発生・・・。

以下、略

どうやらパッケージが自動でインストールされなかったっぽいので、、、

Installing required packages: automake, libtool, pkg-config, libyaml, readline, libksba, openssl....

手動でインストールしたところ、

brew install automake
brew install libtool
brew install pkg-config
brew install libyaml
brew install readline
brew install libksba
brew install openssl

Ruby のインストールも成功
