Well, there were additional issues when connecting a new system. Somehow the new system lacked permission to the .ssh folder in the user profile. When "rhc setup" ran, it created the .ssh folder under root with no permission for the user. After a quick "chown" so that the user had the proper permission, all was well. For all to consider, the error was as follows:
Cloning into 'foobar'...
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
