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.

Provided 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.
