redmine_git_hosting: Connection refused when sshd doesn't listen on default port

Hi,

our ssh server doesn’t listen on the default port 22, which results in the following error:

$ RAILS_ENV=production rake --trace redmine_git_hosting:update_repositories

* Performing manual update_repositories operation from command line :
rake aborted!

Tasks: TOP => redmine_git_hosting:update_repositories

It works when I change the config of the sshd so that it runs on port 22 .

The :gitolite_server_port variable is set to the port on which the sshd listens.
