When I setup my grid with a map in susy
$susy: (
columns: 12,
gutters: 1/4,
math: fluid,
output: float,
gutter-position: inside,
);
It does not like the gutter as a fraction and I have had to change this to a decimal. No big deal but why if the documentation says this is how to do it does it break?

I am using libsass with compass-mixins installed via bower but am pretty sure this happened when I ran with compass.
This is a known bug in libsass, and has already been fixed - but that fix has not trickled down into node-sass
yet.
