x11/kde6: new meta-port -- there is no KDE 6 ...

... but there is

  * KDE Plasma 6-beta
  * KDE Frameworks 6-beta
  * KDE Gear 24.02-beta

This meta-port pulls all of them together.

    +-------------------------------------------------------------------------+
    | This is a very early preview intended for developers and testers only.  |
    | We hope it will be picked up by rolling unstable distros, but it is far |
    | from being ready for day-to-day use yet.                                |

+KDE is a powerful Free Software graphical desktop environment for Linux
+and Unix workstations.
+
+This package does not contain anything by itself -- it is a
+"meta-port" that depends on other KDE packages.  Its sole purpose is
+to require dependencies so users can install this package only and
+have all the KDE stuff pulled in by the port/package dependency mechanism.
+
+x11/kde6 contains the future KDE Frameworks, Plasma Desktop and Applications.
