Comment(by mta@…):

 A number of the ports in the appdefault patch don't work right without the
 system_x11 variant when built on a case-insensitive file system.  This is
 a upstream bug and results from the fact that the app-defaults file name
 is a mixed case version of the executable file name.  This has been fixed
 upstream for some programs and will likely be fixed for others eventually.
 It would be possible to add a post-destroot rule to get around the bug in
 the meantime since the makefile always puts the executable in the
 conflicting file and leaves the other in a *.ad file.
