Created attachment 699870 [details] emerge output net-misc/curl failure is not related, please ignore. Notice that packages emerge fine until dev-python/pypy3 is upgraded, then the next package (mesa) dies in pretend phase with "AssertionError: SRE module mismatch". All later packages fail without a log.
Created attachment 699873 [details] pypy3 merge log Notice "AssertionError: SRE module mismatch" errors in phases after install.
Created attachment 699879 [details] mesa log Mesa was the package scheduled for merging after pypy3, here is its log. No other packages after this one had a log, as seen in the emerge output attachment. I should note that running the original emerge command a second time was successful, so it might be something to do with upgrading pypy3 while it is in use.
