HomebrewでSpiderMonkeyをインストール

今更ながらコンソールでJavaScriptを実行するために。
以前やろうとしたときはたぶんHomebrewに慣れてなかったから挫折したんだろうなー。

➜  ~  brew install spidermonkey

==> make
==> make install

Installing non-executables to "bin" is bad practice.

==> Caveats
This formula installs Spidermonkey 1.8.5.
If you are trying to compile MongoDB from scratch, you will need 1.7.x instead.
