Publishing Rails with SwitchTower

I need a simpler way to get my changes out to the web site. currently I am just copying file by file to FTP but this is tedious and error prone. I have heard that Switch Tower is the tool of choice for deploying Rails apps so here goes:


gem install switchtower


The install seemed to go well with the following dependencies also being installed.


Attempting local installation of 'switchtower'
Local gem file not found: switchtower*.gem
Attempting remote installation of 'switchtower'
Updating Gem source index for: http://gems.rubyforge.org
Install required dependency net-ssh? [Yn] y
Install required dependency needle? [Yn] y
Install required dependency net-sftp? [Yn] y
Successfully installed switchtower, version 1.0.1


Switch Tower needs to make some changes to the current rails app so that it can deploy it.


switchtower --apply-to [full path to rails app]


This seems easy enough but the first run gives me this. After a hour of google searching and drilling down into the gem install I find that the error, is infact, correct, the rails_generator/sripts/generate code does not exist as part if the switchtower install but I don't know where to get it so I am stuck.
