The current stable dev-libs/libchewing-0.3.2 contains a bug, which affects programs depending on it. On app-i18n/ibus-chewing, it causes phonetic symbols not showing while typing, which can probably be considered severe. This problem was fixed in dev-libs/libchewing-0.3.2-r1 as a patch, and fixed upstream in dev-libs/libchewing-0.3.3. Thus, I suggest either: 1. drop dev-libs/libchewing-0.3.2 keyword to ~arch or 2. stabilize dev-libs/libchewing-0.3.3 or 3. make >=dev-libs/libchewing-0.3.3 a dependency of related packages (eg. app-i18n/ibus-chewing)
Now I've dropeed libchewing-0.3.2. closing.
