だめでした。 C コンパイラの問題ですね。

I had the same problem. Installing gcc-4.7 with homebrew (brew install gcc47) and then CC=gcc-4.7 rbenv install 1.8.7-p375 fixed this for me.

I met the same problem, too. The reply from @funkaster was most helpful (thank you!). The exact command stated did not work, so I tweaked to: brew install homebrew/versions/gcc47
The latter worked fine: CC=gcc-4.7 rbenv install 1.8.7-p375

いま gcc-4.9.1 が入ってるんですね。でも 1.8.7 には gcc-4.7 が要るようなので入れていきます。
