As of last commit, jekyll serve fails when using {% ditaa %} without an --alt something:

      Generating...

`render''

The fix so trivial, I'd rather not bother you with a pull request.

In ditaa.rb line 30:

        if @ditaa_options.include? "--alt"
          @alt_text = @ditaa_options.scan(/--alt "([^"]*)"/).last.first
          @ditaa_options = @ditaa_options.sub /--alt "([">]*)"/, ''
        end

My suggestion is to just add else @alt_text = "" and it fixes the bug.
