Setting up Deployment for Ruby on Rails

[sternkm]

I am in the process of doing a deployment install using Mac OSX Workstation and Ubuntu 6.0.6LTS Server and using the Capistrano Concepts video from Peepcode.
I currently have the following installed on the Mac:
Readline-5.1
Ruby-1.8.6
Ruby Gems 0.9.4
Rails
mongrel
subversion
capistrano
termios
MySQL
and the deprec gems.

When I run the cap deploy_with_migrations or try to svn commit I get the following 3 errors:
