何が起きたの？
Ubuntu14.04でrbenv使ってRuby2.1.1入れようとしたら怒られた、としか表現できないんですけど。

どうするの？
Build failure on 2.x and solution (related to readline) #526
rbenv fails to install 2.1.0 on ubuntu 14.04 #528
調べたらそれっぽそうなissueがあったので、この通りにやってみた。
$ curl -fsSL https://gist.github.com/mislav/a18b9d7f0dc5b9efc162.txt | rbenv install --patch 2.1.1
