Socket.io and RedisStore - simple example not work (event.js:66)

I try to run this example: http://blog.rstack.cc/post/node_js__using_socket_io_with_cluster_module

With node.js v0.8.8 and latest Socket.io (0.9.10) installed. But I get this errors: http://pastebin.com/VfzhxNZX

with node.js v0.8.11 error is in event.js:68, instead of :66 when node v0.8.8

Anybody knows why this example can't run?

You need Redis installed on your machine. You can download it here.
