Two packages mutually blocking each other in Gentoo

I try to update and recive error:
>=x11-proto/xproto-7.0.6 (is blocking x11-libs/libX11-1.0.1-r1)

i did uninstalled xproto but my computer had xproto-7.0.5 not xproto-7.0.6

# emerge --search xproto
* x11-proto/xproto
Latest version available: 7.0.7

The solution
