I'm havning the same issue. I heavily modified the calculation code, using a sass function. See this post: http://vvv.tobiassjosten.net/css/px-to-em-with-sass/

New to Sass, Compass and Frameless. Just started and ran into the same error. Does this mean that this framework is broken under Sass by default?
