[Radiant] installing copy/move in 0.6.4

[Grant Blakeman]

Hi, I'm trying to get the copy/move extension installed in 0.6.4, but when I
try to run the rake, it aborts and says:
rake aborted!
The Shards extension is required and must be loaded first!

The weird thing though is that I've already installed the Shards extension
and it shows up enabled in my extensions list. Am I missing a step
somewhere? Has anyone else had trouble getting copy/move running in 0.6.4?

Thanks!
