rvm で Ruby version 2.1.3 をインストールすると Empty path passed to certificates update 的なエラーが発生しました。

% rvm install 2.1.3

Searching for binary rubies, this might take some time.

Ruby 2.1.3 を使おうとすると dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib という libgmp が読み込めないというメッセージが表示されてしまいます。

% rvm use 2.1.3

Using /Users/your_username/.rvm/gems/ruby-2.1.3
dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
  Referenced from: /Users/your_username/.rvm/rubies/ruby-2.1.3/bin/ruby
  Reason: Incompatible library version: ruby requires version 13.0.0 or later, but libgmp.10.dylib provides version 12.0.0

下記のように disable-binary フラグを付けて再インストールをすると直るようです。

% rvm reinstall 2.1.3 --disable-binary
