Shovel Switchtower deployment

Hello,
Iam trying to use Shovel deployment as explained here
http://nubyonrails.com/pages/shovel. Iam currently using windows as my
development environment and nix to deploy the application. I have
changed
all the dispatch.
files to be executable. but when I run

rake remote_exec ACTION=setup_lighty

it asks for my password and installs lighttpd and other stuff, but
fails on task update_code. Here is my error

C:\radrails\workspace\example\lib\tasks>rake remote_exec
