RuntimeError: Unknown -ERR commande en cours d'exécution sur Ruby gem Redis

Question

L'environnement:

Sur RIR, quand je essayer d'initialiser Redis je reçois un RuntimeError. Voici un extrait:

irb(main):001:0> require 'rubygems' 
=> true 

irb(main):002:0> require 'redis' 
WARNING: using the built-in Timeout class which is known to have issues when used for opening connections. Install the SystemTimer gem if you want to make sure the Redis client will not hang.

Est-ce que quelqu'un a déjà rencontré ce problème? Des idées?
