ошибка в ebuild?

пытаюсь собрать media-sound/alsa-util1s-1.0.18 с -midi.
Получаю:

смотрю выше

configure: WARNING: unrecognized options: --disable-sequencer

Это бага?

PS вроде стабильные alsa-utils так же не собираются с -midi...
PPS если включить midi просит собрать alsa-lib с midi...
PPPS еще бага, тока в форуме? ) после "]code[]/code[" всегда идет пустая строка. или это фича?
