port status process question

[tsteven4]

What is the reason that the recent builds of gpsbabel_app from gpsbabel: 
update to 1.7.0 · macports/macports-ports@2c4528c · GitHub 
<https://github.com/macports/macports-ports/commit/2c4528c71390f39dab320170d7fa51fede588dcb> 
don't show up on Install gpsbabel-app on macOS | MacPorts 
<https://ports.macports.org/port/gpsbabel-app/summary>?  For example, 
Buildbot: ports-11_x86_64-watcher Build #4375 (macports.org) 
<https://build.macports.org/builders/ports-11_x86_64-watcher/builds/4375>

thanks
