Rakefile Fixes

It appears that the Rakefile has some invalid syntax.  These fixes allowed rake to run without error.  However, I cannot seem to get the locally compiled version of pdfkit-www to work...(i am relying on your pdfkit-0.1-allfonts.min.js)

When I try to load pdfkit.js into my page I get the following error

    Uncaught Error: missing module ../path

Is there something missing from the build process?  Also, would it be difficult to switch from a rake file to a cake file?  It seems strange to require someone to install ruby to build coffeescript source with Node.js to then be run on their web browser. . ..
