Frequency exists in 2.4.0, but there appear to be some path problems w/
2.4.0.
Try uninstalling 2.4.0 and installing 2.3.0 instead.

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?
