+x11 is required for gnupg2 installation

[CyberneticEntomologist (Michael David Crawford)]

Indirectly through the rebuild of gstreamer1-gst-plugins-bad @1.14.1. Were we to get past that, I expect the rebuild of webkit2-gtk @2.20.3+gtk2+x11 would also require x11.

I do not yet have any X11 clients on my Mac; I don't want to have to install the server until I have need for a client as well.

I don't think there is a log for this problem.

In short:

 $ sudo port selfupdate
 $ sudo port install gnupg2

I just now saw that there is a gnupg21 port. I'll try that next and will report back.

The reason I don't want to install X11 despite having a big disk is because that disk is partitioned, each with a different version of macOS so as to enable compatibility testing with the Kernel Extensions I develop through my consultancy.

gnupg2 does not depend on gstreamer1-gst-plugins-bad or webkit2-gtk. They were already installed, and rev-upgrade just happened to notice that they were broken because it checks all installed ports for linking problems after installing anything.

You can find out what does use them by running port rdependents gstreamer1-gst-plugins-bad webkit2-gtk. You can then decide whether you want to keep those ports installed.
