rbenv build failed on Ubuntu 14.04
rbenv, ruby, ubuntu
Solution
UPDATE: Use Ruby 2.1.2, it fixes this issue.
14.04 is probably shipping with readline 6.3, which uses `rl_hook_func_t` instead of `Function`.
This bug has already been reported and fixed in Ruby (https://bugs.ruby-lang.org/issues/9578), but not released yet.
Until Ruby 2.1.2 comes out (which I assume will contain this fix), you can use a patch to properly support the new `rl_hook_func_t` method. Use this to install Ruby 2.1.1:
curl -fsSL https://gist.github.com/mislav/a18b9d7f0dc5b9efc162.txt | rbenv install --patch 2.1.1

Problem
I've successfully installed rbenv (along with the build tools) on my Ubuntu 14.04 desktop, and that appears to be working fine, but as soon as I try to install ruby 2.1.1, the build fails: ``` daniel@grape:~$ rbenv install 2.1.1 Downloading yaml-0.1.6.tar.gz... -> http://dqw8nmjcqpjn7.cloudfront.net/5fe00cda18ca5daeb43762b80c38e06e Installing yaml-0.1.6...
