The environment:
Ubuntu 9.10 (run within VirtualBox)
Ruby v1.8.7
Redis gem v2.0.6
On irb, when I try to initialize Redis I get a RuntimeError. Here's a snippet:
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.
=> true
irb(main):003:0> r = Redis.new
RuntimeError: -ERR unknown command

Has anybody run into this before? Any ideas?
