error on build #27

I'm about 90% certain this is user error of some nature but I'm not a ruby programmer and I'm lost on debugging this. Thanks for creating what seems to be an much needed addon to Jekyll.

After installing this plugin and the necessary dependencies I receive this error on jekyll build

Any help would be greatly appreciated.

Probably an undefined preset or setting. Error message improvements are on the 2.0 roadmap.
