Created attachment 635778 [details] emerge --info output On ~amd64 arch, I found dev-python/arpeggio-1.9.2 to fail during building. I discovered this during a world update and then I tried it again as a single-package update (emerge -1au dev-python/arpeggio) to reproduce the error. https://bugs.gentoo.org/705078 has a similar error message but from a different package; I can't tell if it may be related. Here is the essential part of the error message, and I am attaching the output of emerge --info as well as the build log. ERROR: Could not find a version that satisfies the requirement pytest-runner (from versions: none) ERROR: No matching distribution found for pytest-runner Traceback (most recent call last): File "/usr/lib64/python3.6/site-packages/setuptools/installer.py", line 128, in fetch_build_egg subprocess.check_call(cmd) File "/usr/lib64/python3.6/subprocess.py", line 311, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['/usr/bin/python3.6', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', '/var/tmp/portage/dev-python/arpeggio-1.9.2/temp/tmpsyylcwx_', '--quiet', 'pytest-runner']' returned non-zero exit status 1.
