`port fetch qt5-qtbase` does not fetch distfiles on macOS 10.15

[king7532 (Ben King)]

How can I fetch the qt5-qtbase distfiles? See the commands below. However, I can successfully port -vs install qt5

% port installed qt5
The following ports are currently installed:
  qt5 @5.12.4_0 (active)

% port search qtbase 
qt5-qtbase @5.12.4 (aqua)
    Tools and Module(s) for Qt Tool Kit 5
...

Maybe lead with that. The port does lots of fiddling based on the OS version.
