 Replying to [comment:7 jeremyhu@…]:
 > Which ports (other than xorg and xorg-apps) depend on these application?
 Nothing in there should.

 The only thing that depends on xlogo (I didn't check all 22 apps) is xorg-
 apps.  The only thing that depends on it is xorg, and the only thing that
 depends on xorg is gnucash-desktop.  I.e., the dependency chain is
 gnucash-desktop->xorg->xorg-apps->xlogo.

 Yes, I agree, gnome-desktop shouldn't pull in xorg.  On the other hand
 these apps won't build at all if you built the X11 libraries with the
 system_x11 variant.  This seems wrong.  At the very least it seems that
 there should be something in the port file to warn people not to install
 them in this case.  You could test for the location of the app-defaults
 directory and abort the install if it's outside the Macports prefix area.
 Letting the install proceed simply to fail later when it can't replace the
 non-Macports app-defaults file is going to be confusing.
