pkgng: How fix dependences?

[Alex V. Petrov]

After recomendation (20130731) in ports/UPDATING I have:

pkg check -d
graphics/ImageMagick has a missing dependency: devel/gio-fam-backend
devel/ORBit2 has a missing dependency: devel/gio-fam-backend
ports-mgmt/packagekit has a missing dependency: devel/gio-fam-backend
editors/spe has a missing dependency: devel/gio-fam-backend
databases/akonadi has a missing dependency: devel/gio-fam-backend
deskutils/alacarte has a missing dependency: devel/gio-fam-backend
[many skipped]

I try:
pkg set -a -o devel/gio-fam-backend:devel/glib20 -y
Result:
pkg: sqlite: columns package_id, origin are not unique (pkgdb.c:3605)

How can I fix the dependence with portmaster or pkgng?
