In order to merge gail-1.9.3 successfully I guessed by reading about
the error (unresolved symbol ATK_ROLE_REDUNDANT_OBJECT in gail.c), that
dev-libs/atk-1.10.3 should also be updated to dev-libs/atk-1.12.3
before merging gail.
The gail-1.9.3.ebuild defines the dependency >=dev-libs/atk-1.7 .
I'm not an expert, but I mean, this should be corrected.
Thanks
Fixed by adjusting the RDEPEND on atk to >=dev-libs/atk-1.12
Filed upstream documentation bug 394492 to hopefully get "New since" tags on
these newer enum values so that it'd be visible in the documentation that the
minimum version needs to be adjusted in configure.in if these new enum values
are starting to be used by another (upstream) project.

Note that gail-1.10.0 (GNOME 2.17/2.18 stuff) already depends on new enough atk
version in its configure.in file, as it needs atk-1.13 at a minimum for other
reasons
