By yemartin:

My understanding of "approximately greater than" (~>) is that

"~> 2.3.12"

means: __2.3.x with x >= 12__

So this commit breaks every Rails 3.x install.
It should probably be this instead:

">= 2.3.12"

If for some reason this is too open-ended (maybe not compatible
with Rails 3.1 yet?) then it can be:

">= 2.3.12", "< 3.1"

Or did I miss something?
