# Nokogiri depends on pkg-config when built with system libraries but it
# doesn't declare this dependency. Unfortunately, bundler provides no way to
# declare additional dependencies and it will install dependencies in
# alphabetical order so it tries to install Nokogiri before pkg-config and
# this fails.
