"stack level too deep" with simple client - any advice?

[Carlos Eberhardt]

Pardon my newbieness (both to Restfulie and Rails).

I'm getting a stack level too deep error when trying to unmarshal the response from Restfulie. It looks like it's a problem in methodize, but I've come up short with my research. Has anyone seen this before? I'd appreciate any tips at all. Thanks!

I'm on Mac OS X Lion with Rails 3.1.0 and ruby 1.8.7 (2010-01-10 patchlevel 249).

Here's what my rails console looks like:

>> h = Restfulie.at('http://localhost:3000/items').get

Sorry for the noise, I should've tried harder. Using RVM I think I fixed that problem. I'm still not able to get the client working quite like examples, however. It looks like I need to dig into the "resource" a bit more than I expected. I'm probably missing something simple.
