Grunt / SASS Build Error

[mkircher]

All, I installed a fresh copy as described and made sure the required SASS version (3.3.0.rc.6) was installed. While running the grunt server command, I got the following:

I'm not a gem or terminal expert, so any help would be great

It appears as if the XCode Command Line Tools (freely available) are a requirement for installing Sass. Please install them and Sass should compile correctly.

I've verified that everything is installed correctly including XCode CLT, registering as a Apple dev and downloading the tools...

Unfortunately that didn't remedy the issue. Is there something else I am missing here?

See if you can follow the new Installation Instructions to ensure that your Ruby version is up-to-date and ready to work with Style Prototypes. Then try running Bundle Install again.

2.0 of Style Prototypes changes how this loop works (it's no longer there, done once on install time and that's it)
