portupgrade:anonymous Not in due from:<name>-<version>

[栗树亮]

Hi guys:

  When I portupgrade a port like xfce4, after inputing =A1=AEportupgrade =
=A8CR
xfce4=A1=AF, then an error happens whose content is =A1=AEanonymous Not =
in due
from:<name>-<version>=A1=AF.

I thought it was caused by pkgdb.db, so a rm pkgdb.db, and rebuilt it =
with
portversion, but when I portupgrade again, the result remains same.=20
