Answer 1

After trying the solution offered by @eveevans I was still having version issues. Then reading the suggestion by @rubyconvict, I thought instead about using the -v option for gem rather than pushing files about.

Here's what I found eventually resolved my struggle with the dreaded "version of mysql2 (0.3.2)" message on DreamHost:

# in mysql, create example_app & example_app_test ...
# ... for the purposes of this example only, production == development db
rails new example_app --database=mysql --freeze
cd example_app
vim config/database.yml
#   change settings for host, user, password ...
#   ... database for test (example_app_test) ...
#   ... & database for production & development (example_app)

vim Gemfile
#   gem 'mysql2', '< 0.3'

gem uninstall mysql2        # if installed: gem list -d mysql2
gem install mysql2 -v 0.2.7 
rake db:migrate     

From there, I can move onto other RoR fun, like perhaps modifying routes (vim config/routes.rb ... however your mileage may vary).
