Ruby 1.9 doesn't allow the lambda to walk up the directory structure to
require the spec helper This is the same issue as with commit:
f6da3339f59bbd9243a03dc1e417b1fed7955c7e

Also, you can't call each on a string in Ruby 1.9 directly since it
doesn't implicitly do a split on \n like it did in older Rubies, but
each_line works all the way back to 1.8.5

We got rid of the '../../spec_helper' style requires, but a few of them snuck
back in in recent changes.  This purges them out, replaced with the header:

    #!/usr/bin/env rspec
    require 'spec_helper'

By running:

    rspec spec --tag ~@fails_on_ruby_1.9.2

We can now just run the specs that pass under Ruby 1.9.  Obviously in
the long term we want to have all the specs passing, but until then we
need notification when we regress.  From now on new code will be
required to pass under Ruby 1.9, and Jenkins will give us email
notification if it doesn't or if we break something that was already
working.

Stub the command method, so it doesn't give an error.

Adds support for use Archlinux's pacman package manager in Puppet.

Originally written by Miah Johnson, with bug fixes from Thomas Hatch and
myself.

I noticed a test failure when I ran the specs without an internet
connection.  Specs should never need an internet connection to pass.

The resource being used for testing didn't explicitly set the provider,
so it ended up using whatever the default provider was on the system on
which it was run.  This was problematic when running the specs on a Mac
since the default provider is pkgdmg and that provider doesn't seem to
be upgradeable.  So when you tried:

    @resource[:ensure] = :latest

You got the error:

    1) Puppet::Type::Package::ProviderPkgutil when installing should use a command without versioned package
     Failure/Error: @resource[:ensure] = :latest
     Puppet::Error: Parameter ensure failed: Provider must have features 'upgradeable' to set 'ensure' to 'latest'
