Deploy hanging at Tasks: TOP => rvm:check

Hi there, I'm experiencing a problem when trying to deploy to an existing server which has worked in the past for a different user. I think rvm is a mult-user install on the target server but I am not a member of rvm group.

cap test_kipling deploy:check --trace

Tasks: TOP => rvm:check

Would really appreciate if someone could offer some guidance?
