This used to be a known problem with Cython:
https://github.com/cython/cython/pull/1631 .  It has been fixed in Cython
0.26.  The issue here is that lxml comes with pre-Cythonized files produced
by Cython 0.25.2.

Apart from waiting for the next release of lxml, you could manually install
lxml.  To do so, download the source, and run:

    pypy3 -m pip install cython
    pypy3 setup.py build --with-cython      # forced re-Cythonize
    pypy3 setup.py install


A bientôt,

Armin.
