Won't compile

Hi, I'm currently trying Aurora and can't get compass watch, or CodeKit (similar to livereload) to compile. Has anyone else had this problem? Is there a current solution? Thanks in advance.

I've tried with nothing in my sub-theme's _variables.scss, essentially making no changes at all, and simple changes there like,

$total-cols: 16;
$main-content-cols: 10;

Here are the errors I keep running into. This is both on my Mac and on my development server using compass watch.

>>> Change detected at 02:43:59 to: partials/global/_variables.scss
    error sass/style.scss (Line 15 of _variables.scss: Undefined variable: "$fourth".)
overwrite css/style.css

On my actual aurora sub-theme's styles.css i see this:

/*
Syntax error: Undefined variable: "$fourth".
