Created attachment 824981 [details] emerge -v dev-python/gpep517 Building dev-python/gpep517 with python_targets_pypy3 fails with a sandbox violation. After building it once with FEATURES="-sandbox -usersandbox", it now builds fine, even with the sandbox enabled. The attached log might not be perfect, since I copy/pasted from the terminal (can't reproduce again).
I think you probably need to fix the timestamps in /usr/lib/pypy*: /usr/lib/pypy3.9 $ pypy3 -m compileall .
Or reinstall dev-python/pypy3. No clue why it happened to you though.
Given that I can't reproduce, I guess we can close this?
Sure.
