so I get 'Undefined mixin 'box-sizing'. from app/assets/stylesheets/partials/_layout.scss.

box-sizing is defined in lib/color.

So this should work. And it did work on Sinatra...

screen.scss

/* Compass helpers */
@import "compass";

@import "lib/color";
@import "lib/typography";

/* Skeleton (NOT ACTUALLY SASS) */
@import "skeleton/base", "skeleton/skeleton", "skeleton/layout";

@import "partials/layout";
@import "partials/sidebar";
@import "partials/prettify";

@import "partials/external";
