You did not download a stable release, you downloaded our current development branch.  If you get the code via git, it is not a release.

It is an imprecise message: you need cython to develop the code *or* to build from our development repository. You checked out our development branch, which the doc currently points to.  

The reason is that we don't track the autogenerated .c files in git, so you have to use cython to generate them unless you download a zip/tar release where we have done the cython step for you.
