rbenv で Ruby1.8.7-p358 インストールするも GCC がなんやら言われた時の対応策
Ruby技術者認定試験を受けようと思い立ち、 Mac OS X 10.8.2 へ Ruby1.8.7 を rbenv 経由でインストールせんとす。 そこで GCC やらなんやらにガタガタ言われての対応を以下に。

rbenv install するも GCC がほげほげとエラー
rbenv install 1.8.7-p358
ERROR: This package must be compiled with GCC, but ruby-build couldn’t
find a suitable gcc executable on your system. Please install GCC
and try again.
DETAILS: Apple no longer includes the official GCC compiler with Xcode
as of version 4.2. Instead, the gcc executable is a symlink to
llvm-gcc, a modified version of GCC which outputs LLVM bytecode.
For most programs the llvm-gcc compiler works fine. However,
versions of Ruby older than 1.9.3-p125 are incompatible with
llvm-gcc. To build older versions of Ruby you must have the official
GCC compiler installed on your system.
TO FIX THE PROBLEM: Install the official GCC compiler using these packages: https://github.com/kennethreitz/osx-gcc-installer/downloads
You will need to install the official GCC compiler to build older
versions of Ruby even if you have installed Apple’s Command Line Tools
for Xcode package. The Command Line Tools for Xcode package only
includes llvm-gcc.

osxにてrbenvを使ってインストールしたrubyのアーキテクチャーがまちまちに、、、 - 駄日記がヒット。 参考にして調査。
readline のバージョン

arch は x86_64

以下をexport した
|

再々実行 rbenv install

うまくいったようだ
確認

まいっか
