+  www/owncloud includes the entire WWWDIR directory structure in pkg-plist.
+
+  This means that if you upgrade it, your config files are added to pkg-plist,
+  and are then removed on the next deinstall.
+
+  This issue has been fixed, but you must back up your install of owncloud and
+  reinstall to avoid data loss;
+
+  # cd /usr/ports/www/owncloud
+  # tar cfC /tmp/owncloud.tar `make -VWWWDIR` .
+  # make deinstall
+  # tar xfC /tmp/owncloud.tar `make -VWWWDIR`
