Glad to hear you got it worked out. For the benefit of others who may encounter the same problem, could you share what you did?
Also, you might be interested to know that I have created a project at https://github.com/habuma/spring-social-roo that shows how I added Spring Social to a Roo project, including a README file with the steps I took. Ideally, you wouldn't need to do this manually, though. Ideally, there'd be a Roo plugin that does it all for you. But that's the subject of https://jira.springsource.org/browse/SOCIAL-312.
