Hi,

I’ve been trying to use the Magic/XML library ([http://chaosforge.org/](http://chaosforge.org/)  
taw/magic\_xml/) to parse some large XML files for my application.  
Everything works fine on my Mac Mini that I’m developing on, but as  
soon I try to deploy to production settings, I get this error:

XML is not a class  
#{RAILS\_ROOT}/lib/magic\_xml.rb:374  
#{RAILS\_ROOT}/app/models/usb.rb:5  
#{RAILS\_ROOT}/app/views/dashboard/index.rhtml:11:in  
`\_run\_rhtml\_47app47views47dashboard47index46rhtml’

Anyone have any ideas as to what would be causing this or how to go  
about troubleshooting?

Thanks for taking a look,  
Tony
