Here is the fix (from Brian Smith, xfig developer):
It seems that xfig crashes with macports now. I don't know if its the new beta version (3.2.5-alpha5) or if its something with macports, because it worked fine with darwin. Basically what happens is that if you to click on the 'File','Edit','View','Snap', or 'Help' tabs it pulls down a blank list and then crashes with this message in the portal:
color = '#ffcccc'
