This is my dumping ground for mucking around with riak
Ripple requires ActiveSupport (and Model?) from Rails 3. To get everything installed:
gem install gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n
gem install rack-mount --version "~> 0.4.0"
gem install rails --pre
gem install ripple
You will also need riak installed. Personally I do this using homebrew. I use the following command to ensure I am not installing from a cached download, and unlinking spidermonkey which gave me issures in the past. The current recipe in homebrew is labeled as riak 0.8 but is actually tip which was giving me issues - a proper 0.8 recipe can be found at http://github.com/lstoll/homebrew/blob/5dd77c682ce5859f3f4ded50c1bc7770e8aa1c44/Library/Formula/riak.rb
brew uninstall riak ; brew unlink spidermonkey ;\
rm /Users/lstoll/Library/Caches/Homebrew/riak-0.8.zip ; brew install riak ;\
brew link spidermonkey
you can then run 'riak start' to get the server up and running
