OK, thanks for the link to the issue. I'm not using virtual environments - I built python3.7 (and 2.7) with the `make altinstall` method. I managed to get the numpy build working on 3.7 by removing the `random/mtrand/mtrand.c` file so that it gets (re-)generated during the build using the latest cython version.

Are you sure that cython is installed in the same virtualenv as you're using to build numpy? If you were using a numpy sdist then it would make sense because we include the pre-generated .c files in the sdists instead of running cython, but given that you're building from a numpy checkout I dunno. -n -- Nathaniel J.
