Answer 1

My guess is that you're running Gentoo with a stable ACCEPT_KEYWORDS (i.e. amd64, not ~amd64). The overlay version is not marked as stable. 1.10.2-r2 is the latest stable version in the Portage tree. You can't specifically force an overlay to take priority so you have two options...

• Change KEYWORDS in the overlay version to make it stable.
• Add "x11-libs/cairo ~amd64" to /etc/portage/package.keywords and add ">=x11-libs/cairo-1.11" to /etc/portage/package.mask.

Answer 2

What I would do in such situation is try and find out the mentioned keywords by either emerge -S or running eix-update (provided you have it installed) and then checking it with eix (which is handy anyways).
