Undefined method error

[AlexeyKupershtokh]

I'm trying to run the package under ubuntu 14.04 and ruby 1.9.3.
It fails with the following error:

Auditing redis://@redis-01.local:6386/ sampling 0 keys
Sampling 601 keys...
./redis-audit.rb:157:in `block (2 levels) in group_key': undefined method `[]' for #<Enumerator:0x0000000289a948> (NoMethodError)

I was running into this problem as well. If you pull this revision: https://github.com/snmaynard/redis-audit/archive/aa9296861bafbf43f5db960343c47c13a66de39b.zip

And then comment out the bundle requirement at the top of the redis-audit.rb file it works on 14.04 w. ruby 1.9.3
