Конда сборка выдает DependencyNeedsBuildingError для несвязанного пакета

Question

Я поднял билет на это, но подумал, что я также хотел бы спросить здесь, видел ли кто-нибудь подобное.

Tl; dr: сборка вроде бы идёт нормально, потом в конце я получаю эту ошибку:

During handling of the above exception, another exception occurred:

conda_build.exceptions.DependencyNeedsBuildingError: Unsatisfiable dependencies for platform win-64: {"poppler[version='<=0.62']"}

Я не знаю почему conda думает, что мне нужно poppler (это не в моем рецепте, или в зависимостях этих пакетов), или зачем ему нужна эта версия. Самая низкая версия доступна для win-64 0,77.

Я думаю, что могу проигнорировать эту ошибку, потому что пакет устанавливается и работает нормально, но я хотел бы, чтобы сборка прошла без проблем, прежде чем я буду уверен.
