I installed the „gv“ port (ghostview). Worked. I can give gv on the

But I’m getting:

I thought, X11 apps can run against the macOS desktop server, can’t they?
Or do I have to run an extra X11-server?
I am not sure exactly what you mean by this, but X11 applications cannot
connect directly to the native (Quartz) window manager in macOS. You
need to run an X11 server on top. Have you installed one of these,
either XQuartz from
https://www.xquartz.org/
or (better these days as the above is effectively no longer maintained)
just run
> sudo port install xorg-server
to install the MacPorts version (which is more up to date than XQuartz)
?? If not, please do this now (I recommend the MP one).
Then, log out and back in again (yes, this is really required).
Then, just start whatever X11 application you want, no setting DISPLAY
or anything like that, and the X11 server will automatically start.
