Okay, try installing the ruby gem pkg-config version 1.1:
$ sudo port select —set ruby ruby23
Selecting 'ruby23' for 'ruby' succeeded. 'ruby23' is now active.
$ sudo gem install nokogiri-1.8.2.gem -- --use-system-libraries
Building native extensions with: '--use-system-libraries'
This could take a while...

Yes, I see that even after installing pkg-config gem, but nokogiri install
proceeds nonetheless.
