`gulp sass` fails

[dkesler]

I cloned the repo and did an npm install and bower install, but when i tried to run gulp i get the following error

$ gulp sass
/Users/david.kesler/ws/oss/ticker/node_modules/gulp-sass/node_modules/node-sass/lib/index.js:22
    throw new Error('`libsass` bindings not found. Try reinstalling `node-sass`?');
    ^

Error: `libsass` bindings not found. Try reinstalling `node-sass`?

Additionally, if i tried to run sudo npm start i get the following error, but im not sure if this is because i can't run gulp sass

$ sudo npm start
