It seems that pyenv cannot install 2.7.18 on Mac M1 (Apple ARM).

This is because the pyenv "recipe" for 2.7.18 fetches openssl 1.0.2 which did
not have ARM support at the time. M1 support was added in 1.1.1i according to
https://www.openssl.org/news/cl111.txt.
So, this change is pulling in the latest of that series at the time of
authoring this change, which is 1.1.1v.
This could also potentially bring more security to 2.7.18.
There is some evidence here that the corresponding Python maintainer tried to
support a more recent OpenSSL version:

For testing, I tried to exercise the Python test suite to see whether the ssl
tests work ok. I have run the following commands to double check that:
pyenv uninstall 2.7.18 (just to start clean)
pyenv install --keep 2.7.18
cd ~/.pyenv/sources/2.7.18/Python-2.7.18
make test
It seems that importing openssl worked. There are some connection resets by
peer in certain threads, but they are not test failures.
