I was attempting to install wraith on a recently-updated debian system. I was encountering this error:
$ sudo gem install wraith
Building native extensions. This could take a while...
ERROR: Error installing wraith:
ERROR: Failed to build gem native extension.
/usr/bin/ruby2.1 extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h
extconf failed, exit code 1
Gem files will remain installed in /var/lib/gems/2.1.0/gems/nokogiri-1.7.2 for inspection.

I looked at the pre-requisites for Ubuntu, and ran all of them. I was only missing libicu-dev.
However, I was not able to install the wraith gem until I installed ruby-dev:
$ sudo aptitude install ruby-dev
The following NEW packages will be installed:
libgmp-dev{a} libgmpxx4ldbl{a} ruby-dev ruby2.1-dev{a}

You might consider adding a Debian section to the pre-requisites and including ruby-dev in it.
Can confirm this for Ubuntu 17.04. ruby-dev package is necessary to install wraith.
I was seeing a similar error

I had followed the second answer here to update ruby https://stackoverflow.com/questions/26595620/how-to-install-ruby-2-1-4-on-ubuntu-14-04, i.e.
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.4
however, ruby-dev was still 1.9 so
$ sudo apt-get install ruby2.4-dev
did the trick for me.
