@all I'm sorry, for some reason I didn't get notifications for the package...
I've added ruby-pkg-config as a makedep, and i'll keep an closer eye on this package.

@skrunc worked, thank you. please add "ruby-pkg-config" as a dependency

@remy, can you add ruby-pkg-config as a dependency of this package? It is required for build.

@JohnRobson I have tried it as jmartl109 stated and it worked. Try installing ruby-pkg-config.

@ArnaudNux You need to install ruby-pkg-config. It should be a dependency (or build dependency?) of this package.

I'm still getting version incompatibility issues with ruby-mini_portile2. Just running

#!/usr/bin/ruby
require 'rubygems'
gem 'nokogiri'

produces

Could not find 'mini_portile2' (~> 2.1.0) - did find: [mini_portile2-2.2.0.rc1] (Gem::LoadError)

But if I edit /usr/lib/ruby/gems/2.3.0/specifications/nokogiri-1.6.8.gemspec and change the mini_portile2 line from "~> 2.1.0" to ">= 2.1.0", it seems to work OK.

Thanks for updating!

But this package now depends on ruby-pkg-config too.

1.6.8 is out.
Also, nokogiri now depends on ruby-mini_portile2 >= 2.1.0, so I guess these issues with mini_portile are finally solved.
