Created attachment 153757 [details] www6to4.patch trim @dirrmtry move pkg-plist -> PLIST_FILES
maintainer approved the changes
As far as I know, "'@sample etc/www6to4/www6to4.conf.sample' " is not legal for PLIST_FILES. When @sample is used, then pkg-plist file *must* be used. I'll remove the one line and just ignore the patch.
