Bug#739775: root-system: Please support building with Ruby 2.0

[Christian Hofstaedtler]

Source: root-system
Version: 5.34.14-1
Severity: normal

Dear Maintainer,

A new ruby-defaults, switching the default Ruby version to 2.0, will be
uploaded soon. (It is available in experimental for testing.)

During a test rebuild of rdepends with the new package, your package
failed to build.

If possible, please change your package in advance to support building
for Ruby 2.0, so when ruby-defaults is uploaded, only a binNMU is
needed.

Hopefully relevant log parts:

The full build log is available at:
http://aws-logs.debian.net/ftbfs-logs/ruby-defaults/failed-logs/root-system_5.34.14-1_unstable.log.gz

Important changes from 1.9 to 2.0:
- location of ruby/config.h has changed; it's location is now available
  from:
  ruby -r rbconfig -e "print RbConfig::CONFIG['rubyarchhdrdir']"
- path for binary extensions has changed; it's location is now available
  from:
  ruby -r rbconfig -e "print RbConfig::CONFIG['vendorarchdir']"


Thank you,
Christian
