[DRE-maint] Bug#788051: asciidoctor: tries to load modules from non-existent directory on start-up

[Chuan-kai Lin]

Package: asciidoctor
Version: 1.5.2-1
Severity: grave
Tags: patch
Justification: renders package unusable

Hi,

The asciidoctor program aborts on start-up with the following error:

/usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- /usr/bin/../lib/asciidoctor (LoadError)
	from /usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require'
	from /usr/bin/asciidoctor:5:in `<main>'

It looks like the program tries to load the asciidoctor module from a directory
that does not exist.  The offending line in /usr/bin/asciidoctor is:

  require File.join File.dirname(__FILE__), '../lib/asciidoctor'

Changing that line to the following fixes the problem:

  require 'asciidoctor'

Thanks,
