Error when starting webrick with "ruby script\server"

I went through the guide located here:

when I try to start up the Webrick server, I get this error:

=> Booting WEBrick…

I’m wondering, is it just me? or is there something in the code that is
causing this? any direction would be helpful. this is probably sparse on
details, but I’m pretty sure I’m not missing anything. check out from
Subversion, generate app through rails command, run web server. it
should work, right?

I checked rails out from trunk.

I think edge is broken on windows. Try a revision before 3761.
