Dispatcher failed to catch: undefined method `read' for class `FCGI::Stream' (NameError)

I have a Rails site hosted on Bluehost, which recently upgraded to
Rails 2.3.3. When they did so, it broke my site, which was frozen to
Rails 2.3.2. In my fastcgi.crash.log I found the following.

[23/Jul/2009:10:00:28 :: 23983] Dispatcher failed to catch: undefined

unhandled dispatch error

To fix the problem, I installed the rack gem locally on my Bluehost
account. I then edited the rack-1.0.0/lib/rack/handler/fastcgi.rb file
and moved line 7, which aliases the read method, to after the read
method definition instead of before it. All was well with the world
again after I told my rails app to use the local gem instead of the
global system gem.

I'd be happy to submit a patch if needed.
