So the problem is that /opt/local/share/ghostscript/9.23/doc is a symlink to a path inside the destroot, which doesn't exist after installation.

The problem was introduced ​here because $(DESTDIR) was erroneously used on the source instead of the target. See also ​here where $(DESTDIR) was then added to the target but not removed from the source.

So this needs to be fixed by removing $(DESTDIR) from the source, the port needs to be revbumped, and the problem needs to be reported to the developers.
