libv8 のビルドで失敗してる。
http://qiita.com/mana-bin/items/0ee8b35c1726bacd8ecf を参考に、 bundle install 時のオプションを変更
$ bundle config build.libv8 --with-system-v8
再度 bundle install。今度は、therubyracer の install に失敗。

http://wknar.hatenablog.com/entry/update-gcc-and-v8 曰く、brew install v8 すれば v8.h が見つかるようになるらしかったので、してみた。

brew install v8 4.80s user 3.18s system 7% cpu 1:43.79 total
この状態でまた bundle install。が、同様のエラー。
v8.h は /usr/local/Cellar/v8/4.9.385.28/include/v8.h にあるが、どうも path が通ってないっぽい？？？？
最終的に
home-brew で古い v8 を install した。
具体的には、brew install homebrew/versions/v8-315 で version 3.15.11.18 を install。
libv8 では —with-system-v8 を指定し、さらに therubyracer install の際には v8-315 の directory を v8-dir として指定するようにした。
$ brew install homebrew/versions/v8-315
$ bundle config build.libv8 --with-system-v8
$ bundle config build.therubyracer --with-v8-dir=/usr/local/opt/v8-315/
