Re: What Version of rail/ruby?

They probably just didn't update that page since 1.8.5 recently came
out. I'm running 1.8.5 with Rails 1.1.6 fine.

I think the problem with 1.8.5 is with breakpoint, which can be
important for debugging Rails apps, but there is a patch available
that fixes it (I think).

breakpoint (actually, Binding.of_caller, which it depended on) relies on a bug
in Ruby that was fixed in 1.8.5 [1]. If you want to keep debugging using
breakpoints under 1.8.5, there are two possibilities:
* use ruby-debug [2]
* use call_stack's alternative Binding.of_caller [3].

If you choose the latter, all you have to do is load breakpoint185.rb in your
server, e.g.
ruby -rbreakpoint185 script/server
and proceed as usual (see [3] for information relevant to RubyGems users,
though).
