That's the problem, then; you're deploying an empty directory. The 'deploy' task (and friends) assume you are deploying a Rails application, and that it conforms to the standard Rails application directory tree.

What is the list of files and directories immediately under /trunk in
your repository:

   http://192.168.1.4/svn/#{application}/trunk

Is /trunk/public a directory?

Check permissions on the parent folder too

Also check for a sticky bit?

Subject: [Capistrano] Re: Troubles deploying first rails application

The following is the error that is causing the deploy to fail:

  ** [out :: 192.168.1.4] ln: creating symbolic link `/var/www/
faresearch/releases/20070225214903/public/system' to `/var/www/
faresearch/shared/system': No such file or directory

But I have no idea _why_ it is causing it to fail. I worked with
another person, who was getting this error when deploying to RHEL,
and he verified that the directories in question all exist. Has
anyone else dealt with this, and come up with a solution? I'm at a
loss.
