When running compass watch from the static/zinnia/sass directory, compass will throw an error message:
error sass/screen.scss (Line 30 of sass/partials/_two-cols.scss: Undefined mixin 'full'.)
you must install compass-susy-plugin (0.9) to run compass.
Note : I do not use yet the latest version of Susy.
Ah, that explain why. I got the problem while I had susy 1.0.1 in my PC. Now after I installed version 0.9, the problem disappeared.
I will do an update soon.
now use Susy 1.0 #170
I use Susy 1.0 but have the same problem.
