　ruby 1.8 の tk ライブラリが OS X 上でビルドできない件です。

　OS X の gcc には仕掛けがあり、 ruby 1.9 が入っていなくても  
#include \<ruby/ruby.h\> は

/System/Library/Frameworks/Ruby.framework/Headers/ruby.h

を拾ってしまいます。(framework名/Headers以下のパス)

　以下の修正で直ります。コミットしてよいでしょうか。

　パッチをよく見てほしいんですが、 #include \<ruby/ruby.h\> はして  
いませんよ。1.9系なのかの判定に使っていて、それがうまくいかない  
理由が上記です。

　実際に #include しているのは \<ruby/signal.h\> なので、同ヘッダ  
ファイルをチェックするようにするのが私のパッチです。
