I am really a beginner.
This is the config.log that is mentioned:
This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was generated by GNU Autoconf 2.69. Invocation command line was
$ ./configure --prefix=/Users//.rbenv/versions/2.6.3 --with-openssl-dir=/usr/local/opt/openssl
