 Updating my quite old macports I was surprised to find xorg-* packages
 being required by one of them, since I had not needed it before for any of
 my installed packages.  [I have Apple's X11.app from the Developers Tools
 installed.]
 It was especially surprising since I was being selective about upgrades
 and checking dependencies as I went.  Eventually I determined libungif to
 be the culprit.

 I understand that substantial changes to ports may make use of new
 packages, and have no objection to this dependence, if it is indeed a new
 one.

 Not being too familiar with the ports system innards, I don't know if this
 is a defect.  Perhaps I am simply not understanding something.  But from
 my standpoint, the following makes no sense (apologies for poor
 formatting):

 $ port deps libungif

 Full Name: libungif @4.1.4

 libungif has no Build Dependencies, Runtime Dependencies, Fetch
 Dependencies, Library Dependencies, Extract Dependencies

 $ port dependents xorg-libX11

 libungif depends on xorg-libX11


 I'm at a loss for what to do with this.  I don't want two X11 systems
 installed.
