During installation, Cython now compiles some of its own modules into C extensions to speed up compilation (by quite a bit, actually). If it can't import them for some reason (e.g. they were built for a different Python version), you will get the error above.
BTW, this does not affect lxml as long as you only use released sources (which do not require Cython).
