Comment (by zacaway):

 I also have this same problem.  I tried
 [http://michaelgalloy.com/2016/11/11/problems-with-xquartz-2-7-11-on-
 macos.html this suggestion], repeated here:

 {{{
 sudo mv /opt/X11/lib/libXt.6.dylib{,.bak}
 sudo cp /opt/X11/lib{/flat_namespace,}/libXt.6.dylib
 }}}

 but this didn't work for me.

 When I first tried to install ddd I got this message:

 {{{
 Error: Failed to archivefetch openmotif: xorg-libXt must be installed with
 +flat_namespace.
 }}}

 So I installed xorg-libXt with +flat_namespace and then the ddd
 installation completed.

 {{{
 port install xorg-libXt +flat_namespace
 port install ddd
 }}}

 Any other suggestions would be welcome.
