I installed facets 2.4.0 (the current latest) and tried to use the
'frequency' method shown in this example, but in doesn't exist in this
version of facets.

I did 'ri facets' and it only returned 'Enumerable#frequency'
This is using Linux (PCLOS) and Ruby 1.8.6-p114.

What version of facets does the 'frequency' method exist in, because
it isn't in version 2.4.0?
