[DRE-maint] Bug#993818: ruby-nokogiri: WARNING: Nokogiri was built against libxml version 2.9.12, but has dynamically loaded 2.9.10

[Pirate Praveen]

Package: ruby-nokogiri
Version: 1.11.7+dfsg-2
Severity: serious
Justification: migration to testing blocked

autopkgtest for cewl is failing in testing

terceiro on irc:
this type of warning is a PITA; I usually patch them out
(after checking that the package does work with whatever version we 
have in debian :))
just checked, the dependency is automatically generated; probably 
patching to remove the check and warning is the way to go
