Comment (by eirnym@…):

 I prefer strategy from FreeBSD ports if we tell about different versions.
 In this case FreeBSD ports we'll have several qt5-mac ports with different
 or same patches, but they'll be incompatible with each other and have
 different characteristics. Something like qt5-mac-5.4, qt5-mac-5.5,
 qt5-mac (for the latest version), etc.

 Yes, on the latest systems, we might install on of several ports, but we
 guarantee compatibility with previous systems, and include the newest one.
