Rails - Dec 2012 - ActiveSupport Dependencies load eats MultiJson.load?

I can''t quite figure out what''s going on here, it seems like
if this were
actually a problem someone else would have run into it and I''d have
better
luck googling for it, since MultiJson is so popular but....

Rails 3.2.9.  Is ActiveSupport::Dependencies doing something weird with a 
#load method defined on all objects, such that it conflicts with other 
objects #load method?

MultiJson wants you to use MultiJson.load to parse JSON. 

But when I try.... somehow some activesupport load is eating it instead. I 
get an error "Could not load file [big json string]", and this odd 
stacktrace:

activesupport-3.2.9/lib/active_support/dependencies.rb:245:in `load''
activesupport-3.2.9/lib/active_support/dependencies.rb:245:in `block in 
load''",
active_support/dependencies.rb:236:in `load_dependency''",
activesupport-3.2.9/lib/active_support/dependencies.rb:245:in
`load''",

line to my app code that''s actually calling MultiJson.load, but then
the
next line up is an active_support load instead, what now?

Anyone have any idea how I would debug this further, or what might be going 
on?  Any known problems with ActiveSupport adding a ''load''
which kills
other gems loads?

Nevermind!

Indeed, nobody else reported the problem because there is no problem. 

Due to weirdnesses of my Gemfile.lock, I was using a really old version of 
multi_json without realizing it, one that lacked the #lock method. 

(Had an old version of Capybara in my gemfile.lock, which locked multi_json 
dependency to an old version of multi_json, which kept multi_json from ever 
updating, bah).
