Solution

This error appears because the machine that holds your repo does not have tar installed (windows). You should have no problems when moving your :repo_url to your production server or any other server with a linux distribution.

** Edit

Before moving the repo, you could try to set the :copy_compression as :zip in your production.rb

if that fails (it might), and you absolutely want/need to stick to microsoft, there will be no way around installing cygwin with tar enabled on the machine your repo lies on and adding cygwin to your PATH variable.

Check this google discussion for more information.
