Well, the error message is pretty clear that the problem is "the OpenSSL
lib", so if you look on that wiki page for information about the OpenSSL
lib, you'll hit the following subcomponent of that page:


It specifically calls out archlinux with an indication that this ancient
version of python requires an openssl version less than 1.1 (and
mentioning the name of the CFLAGS and LDFLAGS you'll need to
successfully compile ancient python in such cases).

This matches the official python2 documentation:

"Changed in version 2.7.13: Updated to support linking with OpenSSL 1.1.0"

These log lines are useless, your problem has nothing to do with running
