storyboard install notes already had homebrew and most of the requirements there. Ghostscript need a couple of goes to install it gem install storyboard failed as I could not write to a library so had to use sudo ERROR: Error installing storyboard: levenshtein-ffi requires ffi (~> 1.1.5, runtime) johnj:~ john$ gem install ffi again needed sudo ERROR: Error installing storyboard: storyboard requires Ruby version >= 1.9.3. so installing ruby via brew install ruby, not sure if this is a good idea? Seemed to work I needed to add /usr/local/opt/ruby/bin at the top of the /etc/paths file After installing Ruby via homebrew. I did this with TextMate via the mate command, cd /etc;mate paths Then I could install storyboard with gem install storyboard Then needed to upgrade ffmpeg I decided to keep on the homebrew trail so brew install ffmpeg
