portupgrade, xfce4 problems

[Sniper]

I have strange problem with portupgrade.




--$ sudo portupgrade -a
** Port directory not found: x11/libxfce4mcs
** Port directory not found: x11-themes/xfce4-icon-theme
** Port directory not found: sysutils/xfce4-mcs-manager
** There are errors in a meta info for xfce4-mcs-plugins-4.4.3
** Run 'pkgdb -F' to interactively fix them.


When i try pkgdb -F

--$ sudo pkgdb -F
