[Bug 1170801] [NEW] puppet needs to use ruby1.8

[Tim Spriggs]

Public bug reported:

On a new raring install I have added puppet (which brings in facter) but
puppet won't start:

# service puppet restart 
 * Restarting puppet agent                                                                                                                   /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- facter (LoadError)
	from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
	from /usr/lib/ruby/vendor_ruby/puppet.rb:9:in `<top (required)>'
	from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
	from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
	from /usr/lib/ruby/vendor_ruby/puppet/application.rb:272:in `initialize'
	from /usr/lib/ruby/vendor_ruby/puppet/util/command_line.rb:60:in `new'
	from /usr/lib/ruby/vendor_ruby/puppet/util/command_line.rb:60:in `execute'
	from /usr/bin/puppet:4:in `<main>'

Looking at facter, it is apparent that it is only available under
ruby1.8:

% dpkg-query -L facter | grep -c ruby/1.8
83
% dpkg-query -L facter | grep -c ruby/1.9
0

However, /usr/bin/puppet is set to use ruby-1.9.1. Manually changing it
to use ruby1.8 allows puppet to start.

Additionally, puppet (<3.x) is known to only run on ruby <1.9.x.
