It looks like bug #434138 is resolved, so we need to update windowmaker (to -r1) to reflect that. I am not sure what is the correct syntax, but since it seems to depend more on scim (than scim-anthy), my guess is: RDEPEND="${DEPEND} nls? ( >=sys-devel/gettext-0.10.39 ) !=app-i18n/scim-1.4.14[gtk3]" This is what I just tested on my system and it seems OK.
FYR, I added it to my tree: https://github.com/thinrope/pkalin/commit/afc9082b456ea45d9a1885379ce755bea6dd9ac5
