Ошибка компилятора при установке python-igraph: Предупреждения, обработанные как ошибки

Question

Попытка установить python-igraph с помощью pip для Python 3, я получаю следующую ошибку компилятора. Могу ли я что-то изменить или это ошибка в igraph? Обратите внимание на строку cc1: some warnings being treated as errors в конце - если это просто предупреждения, могу ли я как-то их игнорировать?
