at-spi2-atk and at-spi2-core are required for >=gtk+-3.6; in addition, at-spi2-core is needed for webkit-gtk-1.8.x[webkit2], and is always required for >=webkit-gtk-1.10.
Therefore, please keyword the following ebuilds (as well as any higher versions/revisions, if they should be added to gx86 before you get to this bug):
=app-accessibility/at-spi2-core-2.4.2 alpha ~ia64 ~ppc ~sparc
=app-accessibility/at-spi2-core-2.6.0 ~alpha ~ia64 ~ppc ~sparc
=app-accessibility/at-spi2-core-2.6.1 ~alpha ~ia64 ~ppc ~sparc
=app-accessibility/at-spi2-atk-2.4.2 ~ia64 ~ppc ~ppc64 ~sparc
=app-accessibility/at-spi2-atk-2.6.0 ~ia64 ~ppc ~ppc64 ~sparc
=app-accessibility/at-spi2-atk-2.6.1 ~ia64 ~ppc ~ppc64 ~sparc
Note that the 2.6.x ebuilds are currently masked.
@alpha: please stabilize =app-accessibility/at-spi2-core-2.4.2 and remove the webkit-gtk[webkit2] entry from profiles/arch/alpha/package.use.mask
@ppc, @ia64, @sparc, after keywording at-spi2-core, please remove the webkit-gtk[webkit2] entries from profiles/arch/powerpc/ppc32/package.use.mask, profiles/arch/ia64/package.use.mask, and profiles/arch/sparc/package.use.mask respectively.
@alpha, sorry, slightly messed up the table: the only thing you should do is stabilize =app-accessibility/at-spi2-core-2.4.2 and unmask webkit-gtk[webkit2]; the ~alpha keywords were already done.
