pdfium_ruby not working under ruby 2.3.1

[agnewtj]

Just tried to install pdfshaver in the latest xenial distro. Used the default system ruby (now 2.3.1), which worked when 2.3.0 was the ubuntu default. The make seems to work, but here's what I get when I require 'pdfshaver':

pry -e "require 'pdfshaver'" LoadError: /var/lib/gems/2.3.0/gems/pdfshaver-0.0.3/lib/pdfium_ruby.so: undefined symbol: FPDFAPIJPEG_jpeg_destroy_decompress - /var/lib/gems/2.3.0/gems/pdfshaver-0.0.3/lib/pdfium_ruby.so from /var/lib/gems/2.3.0/gems/pdfshaver-0.0.3/lib/pdfshaver.rb:13:inrequire_relative'
`

If feels like the fpdf api library is not linking properly.
