Ошибка установки Python netCDF4

Я пытаюсь установить пакет netCDF4 для python 2.7 на Ubuntu 14.04 с

sudo pip install --user netCDF4

Установка завершается со следующей ошибкой:

error: unknown file type '.pyx' (from 'netCDF4/_netCDF4.pyx')

Единственный намек, который я нашел в других темах, заключался в том, что это как-то связано с pyrex/Cython. Любая идея, что я могу сделать, чтобы исправить это?

Вот весь вывод установки:
