Comment (by RJVB):

 Bummer that they made it a required dependency (I have no idea what they
 need an "open collaboration services API" for).

 It's not a difficult port to implement:
 https://github.com/RJVB/macstrop/blob/bf9aa65160e3dfef4d83133b657a4c1ef7659555/kf5/KF5-Frameworks/Portfile#L470

 (but there's a bunch of hidden code there of course). There's only a patch
 to prevent headerfile/directory aliasing on case-insensitive filesystems.

 Qt4 being broken on arm64 may not be unfixable: Apple aren't the first to
 use that architecture in "real" computers and DebUntu have been providing
 Qt4 packages for it: https://launchpad.net/ubuntu/+source/qt4-x11/4:4.8.7
 +dfsg-7ubuntu1 . Maybe you'll find your fix in their patches.
