On Windows it's pretty difficult, simple steps as in that doc may not work
for everyone. You may be happier using Docker:
http://scipy.github.io/devdocs/dev/contributor/quickstart_docker.html

That said, if you want to make the Windows build we can try to help. The
above error can have multiple causes, so please put your whole build log in
a gist and provide us with a link to it.

Cheers,
Ralf
