bsduck Ok! This is strange... something went wrong with the latest build but it got uploaded to the server anyway. I haven't really noticed it since the packages that are missing were already installed on my system.
In case you'd be interested, which obviously you no longer are, there's a follow-up build that should hit the mirrors in a few days.
EDIT: For example, this shouldn't happen...
pin@mybox $ pkgin avail | grep qt5-qtmultimedia
qt5-qtmultimedia-5.14.1 Qt5 module for multimedia
qt5-qtmultimedia-5.14.1nb1 Qt5 module for multimedia
While waiting you can always update the base...
pin@mybox $ uname -v
NetBSD 9.0_STABLE (GENERIC) #0: Tue Mar 10 06:49:58 UTC 2020 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC
or, do something else ;)
Soon it will all be fine again.
