While working to enable pypy3 support for numpy I encountered the following. Running `FEATURES=test; for e in *.ebuild; do ebuild $e test; done` on dev-python/numpy produces errors on all versions less than 1.19.0. They are all of the form FAILED f2py/tests/test_return_real.py::TestF77ReturnReal::test_all[s8] - AttributeError: 'NoneType' object has no attribute 'split' these errors do not occur when those version of numpy are testing in git using the same pypy3 build. I have attached the 1.18.5 build log for the record, the errors for versions in tree less than that are the same.
please try to attach again. https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
