[DRE-maint] Bug#711079: bundler: Bundler is incompatible with chruby

[Alex Young]

Package: bundler
Version: 1.1.4-6
Severity: normal

Dear Maintainer,

The /usr/bin/bundle binary supplied by the bundler package uses
"#!/usr/bin/env ruby" as its shebang line.  This means that when I run
`bundle install` with a non-system ruby enabled, and I don't have the
bundler gem separately installed, the `bundle install` command fails
with the following output:

$ bundle install
/home/alex/.rubies/ruby-2.0.0-p195/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- bundler (LoadError)

from /home/alex/.rubies/ruby-2.0.0-p195/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'
    from /usr/bin/bundle:2:in `<main>'

This is specifically a problem when using chruby (and chruby-exec) to
select the activated ruby.

The `bundle` package should specify the system ruby to run with,
otherwise `require "bundler"` will fail to see the installed libraries
at /usr/lib/ruby/vendor_ruby/bundler.  Replacing the shebang line with
"#!/usr/bin/ruby" fixes this.
