                    Cannot use the font files with the latest
                    x11-fonts/libXfont, and take maintainership

           Version: Latest

                OS: Any

As described in bug #225125, japanese/font-kanji18 and japanese/font-kanji26
has not been usable since the latest update of x11-fonts/libXfont
(CVE-2017-16611).

Because these ports installs font files as symbolic links,
and the latest x11-fonts/libXfont does not handle other than regular
font files.

* How to fix

(1) Install font files to ${FONTSDIR} instead of ${DATADIR}.
(2) Stop to make symbolic links from the font files to 
    ${PREFIX}/share/fonts/misc/, which is found in the default font path.
(3) Add pkg-message.in to display additional font path settings
    (Copied from head/japanese/k10, r397891 with typo fix).

And I take the maintainership.
