Pyenv and Python 3.9.1. - BUILD FAILED on Big Sur - config.log file

gistfile1.txt

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by python configure 3.9, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/Users/andreamoro/.pyenv/versions/3.9.1 --libdir=/Users/andreamoro/.pyenv/versions/3.9.1/lib --with-openssl=/Users/andreamoro/homebrew/opt/openssl@1.1
