$ ri Enumerable#count
Nothing known about Enumerable#count
$ ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.9.1]
Could it be specific to a Ruby version? The error I got was a method
Is this method specific to 1.9 ?
I changed the ambition code to:
remove_method :find, :find_all
Which solved the problem.
