Comment (by reneeotten):

 this is indeed an annoying problem, but it as Ken said it only appears on
 newer systems... Adding {{{use_xcode yes}}} "fixes" the problem on newer
 systems, but now also requires users on older systems to have a full XCode
 installation while there that isn't necessary. That's the reason I've been
 reluctant to add for ports that report this problem (i.e., [ticket:65294]
 or [ticket:65107] or [ticket:64884] as I don't consider this the correct
 fix. Having said that, I also don't have the time or motivation to
 investigate this more thoroughly and see if there is another way to fix
 this.

 Perhaps if one could identify on which systems this is causing trouble we
 could add the {{{use_xcode yes}}} conditionally to the {{{qt5}}} PG -
 although that might cause other, possible non-reproducible build, issues.
