cl-openglパッケージを登録

darcsでダウンロードしたフォルダをsbclに登録する．

1. フォルダ全体を/usr/local/lib/sbcl/site/に移動．

$ mv ~/cl-opengl/ /usr/local/lib/sbcl/site/ 

1. cl-opengl/*.asdファイルからsite-systemsフォルダ内にシンボリックリンクを作成

$ cd /usr/local/lib/sbcl/site-systems
$ ln -s ../site/cl-opengl/*.asd .

これで完了．

1. あとはasdfでロードできる．

 * (require :asdf)

("ASDF")
 * (asdf:oos 'asdf:load-op :cffi)

※最初にロードしたときはコンパイルが実行される．
しかし，glutについては，ライブラリをインストールしていないので，以下のようにエラーが出力される．

 * (asdf:oos 'asdf:load-op :cl-glut-examples)
