none of these work because they are private? see example here of workaround

correcting myself - looks like it just needs to be invoked like this

require 'rubygems/text'
extend Gem::Text
p levenshtein_distance("asd", "sdf")

Yes, I would not have known myself if havenwood would not have
pointed out to me, a few years ago, that levensthein-calculation
exists within the Gem namespace (I make use of it in one gem that
deals with bioinformatics of some sorts; there the levensthein
distance can be useful to assess differences between
nucleotide/aminoacid sequences).

I think this is not a bug but more like a suggestion to enhance
the documentation - perhaps one or two examples could be added.

PS: The Gem namespace has quite a few nifty things; I especially
like to compare version of programs, and
if you ever need the registered licenses, you can use
Gem::Licenses::IDENTIFIERS - there is a lot of useful stuff
within Gem; finding them is not always trivial though.

Gem::Text is a Module. It's expected behavior.
