Does anyone have experience using Capistrano with the
capistrano_rsync_with_remote_cache gem in a WindowsXP/Cygwin
environment? Is there a better or more-preferred method for
expeditiously updating remote servers? I describe the problem that
I'm having below along with pertinent information.
Thank you for your time!

The Problem
I successfully deploy my Rails application using the standard
Capistrano recipe (tarring an SVN directory and SFTP’ing it to the
remote server) and now I would like to use the rsync gem in place of
the standard recipe. Steps 1 and 2 of the rsync deploy work
perfectly. The problem is that the I get a “broken pipe – send (2)”
error when I try to communicate with the remote server in step three.
Although the copy SVN copy from my local pc to the remote server was
successful in step 2, the rysnc command appears to break the ssh
connection (see the console output below).
My Environment
Windows XP, Cygwin, and native Cygwin ruby. I know you said that the
gem has not been tested in a windows environment, but that’s where I
currently have to be.
