[Rails] Rails on mod_ruby

[Eric Anderson]

I am trying to get a simple "hello world" up and running on my server 
with mod_ruby. I think I got everything done but I am getting an error. 
I have copied and pasted the stacktrace at the bottom of the message. 
Any help would be greatly appreciated. The only reference to this 
problem was the following URL:

http://groups-beta.google.com/group/comp.lang.ruby/browse_thread/thread/53c6c8a6183810ea/d2bf3b5e8e1deafd?q=in+%60undef_method%27:+undefined+method+%60extend_object%27+for+%60Singleton%27+(NameError)&_done=%2Fgroups%3Fhl%3Den%26safe%3Doff%26c2coff%3D1%26q%3Din+%60undef_method%27:+undefined+method+%60extend_object%27+for+%60Singleton%27+(NameError)%26qt_s%3DSearch+Groups%26&_doneTitle=Back+to+Search&&d#d2bf3b5e8e1deafd

but I don't completely understand the discussion and therefore don't 
really understand how to go about solving my problem. Also there was a 
small bug in the latest rails package. The new_controller script seemed 
to have an extra "end" keyword at the end of the file. I just removed it 
and everything worked fine.

Thanks,

Eric
