Running mod_ruby

Hi, I’m having trouble running my application with mod_ruby on Apache2.
I’ve set them up like this:

httpd.conf:

RubyRequire apache/ruby-run RubySafeLevel 0 SetHandler ruby-object RubyHandler Apache::RubyRun.instance

public/.htaccess:

RewriteRule ^(.*)$ dispatch.rb [QSA,L]

And when I run the app I get the awful error msg:
“Application error
Rails application failed to start properly”

And the Apache logs show me this:


[Tue Sep 05 18:22:01 2006] [error] mod_ruby: error in ruby
[Tue Sep 05 18:22:01 2006] [error] mod_ruby:

[Tue Sep 05 18:22:01 2006] [error] mod_ruby: from
/usr/lib/ruby/1.8/apache/ruby-run.rb:53:in `handler’

Please help, I’m stuck and need to get this working asap.
Thanks a lot.
