Building native extensions. This could take a while...

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /root/.gem/extensions/x86_64-linux/3.4.0-static/enumerable-statistics-2.0.8/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /root/.gem/gems/enumerable-statistics-2.0.8 for inspection.
Results logged to /root/.gem/extensions/x86_64-linux/3.4.0-static/enumerable-statistics-    2.0.8/gem_make.out

Could the main README mention what else is needed here? I tend to check github README first and often can not see what is going on and why something failed to install when mkmf.rb is involved.

What is your platform?

BTW, the error message has a hint:
