capistrano failure - where is cap deploy defined?

My run of cap deploy fails, and I think it's because of a formatting issue. Here's some output:

* executing "rm -rf /var/www/cap-deploy/socialmit/releases/20101215141011/log /var/www/cap-deploy/socialmit/releases/20101215141011/public/system /var/www/cap-deploy/socialmit/releases/20101215141011/tmp/pids &&\\\n      mkdir -p /var/www/cap-deploy/socialmit/releases/20101215141011/public &&\\\n      mkdir -p /var/www/cap-deploy/socialmit/releases/20101215141011/tmp &&\\\n      ln -s /var/www/cap-deploy/socialmit/shared/log /var/www/cap-deploy/socialmit/releases/20101215141011/log &&\\\n      ln -s /var/www/cap-deploy/socialmit/shared/system /var/www/cap-deploy/socialmit/releases/20101215141011/public/system &&\\\n      ln -s /var/www/cap-deploy/socialmit/shared/pids /var/www/cap-deploy/socialmit/releases/20101215141011/tmp/pids"

(Sorry for the formatting.)

The &&\\\n things look really fishy, and indeed dumping them into my console causes an output of `\n: command not found.

WHere is cap deploy defined? It looks like the issue has something to do with it being defined as a list of commands that aren't properly formatted, leading to the extraneous newline that is throwing stuff off. But I can't find the actual code for cap deploy to fix it. It doesn't seem to be an app-specific thing since it's not in my Capfile or any of the files referenced by the Capfile.

The issue was that some user-defined tasks named after_symlink had to be renamed and invoked after the symlink using the after("deploy:symlink", "deploy:new_name") syntax:

problem:

namespace :deploy do
  desc "Symlink the upload directories"
  task :after_symlink do
    #run "mkdir -p #{shared_path}/uploads"
    run "ln -s #{deploy_to}/shared/db #{deploy_to}/#{current_dir}/db/link"
  end
end

error (actually a warning):

Deprecation Warning] Naming tasks with before_ and after_ is deprecated, please see the new before() and after() methods. (Offending task name was after_update_code)
[Deprecation Warning] Naming tasks with before_ and after_ is deprecated, please see the new before() and after() methods. (Offending task name was after_symlink)

correct way of doing it:

namespace :deploy do
  desc "Symlink the upload directories"
  task :link_db do
    #run "mkdir -p #{shared_path}/uploads"
    run "ln -s #{deploy_to}/shared/db #{deploy_to}/#{current_dir}/db/link"
  end
end

after("deploy:symlink", "deploy:link_db")

The issue with the \\\n business was a misdiagnosis on my part. Apparently that is executed fine.

The deploy task is defined in the gem here.

I'd say that's most likely not the problem though. What error is it raising when the deploy fails?
