unable to run ckpackager.jar (on a mac)

i'm trying to repackage the source. i need to build in support for figcaption element which is not in dtd.js.

my attempts to run ckpackager.jar have not worked:

$ java -jar ckpackager/bin/ckpackager.jar ckeditor.pack

i'm working on a mac, which is why you see the path /Library/Java/Extensions. i gather that the ckpackager is trying to access some js files. this is new to me - why is the jar trying to access those files? shouldn't the jar be self-contained? i have minimal java experience, but i did try to specify a classpath with the java command. that did nothing to help me source _source/includes/ckpackager.js.

perhaps if someone could help me to understand how i am to source _source/includes/ckpackager.js, i can sort out the rest.

and if anyone has done this on a mac, i would love their help.
