I am following the Quickstart on Github for installing Paperclip and getting an error when trying to migrate my database. I have included error from terminal below. I am using Mac OSX. I think this has something to do with Imagemagick but not sure. I have paperclip 2.6.0 and Rails 3.2.0. If someone knows the answer I would be incredibly grateful as I have not found after hours of searching.

Tasks: TOP => db:migrate

usersrather thanuser. I mistakenly copied verbatim what they had and in the migration directions in the Quickstart Guide it said,rather than
