Comment (by jebickelcsu):

 I tried this and get:

 (gwyddion:38121): Gtk-WARNING: cannot open display:


 So then I typed: which xauth and get xauth not found.

 Do I need to install a version of X11?  As I was reading the macports
 install yesterday it seemed like all that was needed was Xcode, but I may
 have misunderstood.  I thought X11 or Xquartz was only needed on the older
 MacOS.

 Thank you for your help!
