jclouds binding to deltacloud requires a minimum server version of 0.1.0.

The identity and credential specified in jclouds will pass through deltacloud to 
the backend, such as gogrid.

  * OS/X and jruby
    # use homebrew or equiv to install jruby
      * brew install jruby

        * brew link openssl
      # install jruby ssl
        * jruby -S gem install jruby-openssl
      # setup cert directory
        * mkdir $HOME/certs
        * curl -o $HOME/certs/cacert.pem http://curl.haxx.se/ca/cacert.pem
      # rehash cert directory

        * export SSL_CERT_FILE=$HOME/certs/cacert.pem
        * c_rehash
      # test
        * jruby -ropen-uri -e 'p open("https://encrypted.google.com")'
          * should see something like #<StringIO:0x5330cb4b>
