I assume gitblit is something like gitosis or gitolite. These let a user ssh in to a server to access a git repository, but they limit the commands they can run to git-shell. In order to use git-annex get/copy to such a repository, it needs to be able to run git-annex-shell, which is like git-shell but with more commands available. If gitblit can be made allow git-annex-shell to be run, it will work.
