Hi all, I'm not able to use 'imread()' with the octave version provided with ports since it uses GraphicsMagick unpatched (the patch I'm talking about concerns a widespread problem and can be found here 
More generally, is there a way to patch a port before building it? Or, is there a way to tell ports to use an already existing dependency lib instead of fetching and configuring their own?
