I've just added dev-ruby/capistrano-2.5.0 to CVS. This version has two new dependencies: dev-ruby/net-scp and dev-ruby/net-ssh-gateway that are currently not keyworded for your arch. For this reason I have dropped your keywords from dev-ruby/capistrano-2.5.0. Could you please verify that these work on your arch and re-keyword dev-ruby/capistrano-2.5.0 and the new dependencies? I assume things will work fine with this since all packages are pure ruby implementations.
