Deprecation Warnings:

Using `should` from rspec-expectations' old `:should` syntax without
explicitly enabling the syntax is deprecated. Use the new `:expect`
syntax or explicitly enable `:should` with `config.expect_with(:rspec)
{ |c| c.syntax = :should }` instead. Called from
/tmp/buildd/ruby-redis-namespace-1.4.1/spec/redis_spec.rb:26:in `block
(2 levels) in <top (required)>'.

If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.
