Font Awesome is missing?

https://github.com/GitbookIO/gitbook/blob/master/theme/stylesheets/website.less#L3

This line prevents me from compiling the less for the default theme.

Font-Awesome is installed using bower: https://github.com/GitbookIO/gitbook/blob/master/bower.json#L11

For building the theme (js/css), you need to run the grunt command.
