Comment (by mouse07410):

 > Depending what is causing the write error, this might be an issue with
 the machine you are using to build. Are there reasons to think that might
 be the case?

 None, AFAIK.

 This failure is consistent on four different machines, some under
 corporate management, and some aren't. The commonalities between them are:
 MacOS Mojave 10.14.4, Xcode-10.2.1, Macports-2.5.4 (latest stable).

 "write error" could be due to permissions...?

 Also, I was unable to find {{{qtprofilesetup.h}}} anywhere on my machines
 (another ticket mentions it).
