Cool work, I wonder how hard would it be to compile the 1st browser/editor[1]. I have seen few source code repositories with it's code[2], but I'm not sure if it's complete source or not.
I have tried to compile the browser/editor, the worldwideweb.app, as well and failed, indeed due to having incomplete sources/dependencies. I did not look into it too much though with my main goal being to get music software running.
