以前，Debian Wheezy amd64にRuby 2.0.0をインストールした時の
メモどおりにインストールしました．
参照 ⇒ Debian Wheezy amd64にRuby 2.0.0をインストールする
前回とは違った点，気付いた点を書きます．
\curl -L https://get.rvm.io | bash -s stable --ruby上記コマンドを打った後，以前とは違いsudoのパスワードを求められ，
裏で’apt-get update’コマンドが走り，
他に必要なパッケージである’libreadline6-dev, libsqlite3-dev, sqlite3, autoconf, libgdbm-dev, automake, bison, libffi-dev’
がインストールされました．
前のWheezyは開発環境がインストールされていたのですが，
今回のJessieにはまだソースコードからインストールできる環境が
整備できていなかったのでコンパイルに必要なパッケージを自動で検出し
インストールしてくれました．感謝．
最後に今回のログを載せておきます．
Please read and follow further instructions.
