See the attached log.

Upstream tarballs:

• ​https://github.com/Normaliz/Normaliz/releases/download/v3.2.1/normaliz-3.2.1.tar.gz

• ​https://pypi.python.org/packages/5e/8e/2e4f68fb395ea834be0bdd3adf3c1787e320cbb6007e0c16ff6529480ed9/PyNormaliz-1.5.tar.gz to be renamed PyNormaliz?-1.5.tar.gz

The new upstream version 1.5 has some 32/64-bit work. Could you test this?

Updating pynormaliz requires an update of normaliz, which installs and self-checks correctly, but i get the following doctest failure:
