Ckeditor 3.7.0.rc2 in production heroku doesn't work

[soulnafein]

I'm copying straight from the stackoverflow question I found: http://stackoverflow.com/questions/9218521/rails-3-1-on-heroku-ckeditor

"The problem is that the ckeditor/vendor/skins/(kama) or (office2003) or (v2) /editor.css files contains an error that makes the sass compiler scream. The error like this "filter:;", since there is no value it does not work."

Yep, I had the same issue, had to delete the filter:; bits and a couple of other things as well that I don't remember atm.
