[MacRuby-devel] rss module throws exception on including

[Jakub Suder]

Hello,

I tried to implement a sample photo RSS application according to  
Apple's tutorial "Building a RubyCocoa Application: A Tutorial" using  
MacRuby. However,  I'm getting such error:

----

This error can be reproduced by simply running macirb from the  
terminal and doing require 'rss'. Same thing happens when I download  
the latest version of the file dublincore.rb and include it. What's  
interesting is that this error isn't displayed when I include the same  
file using plain irb. This probably means that it's not a bug in that  
file, but in the parser that interprets it.

I've tried to download and compile the latest version from trunk and  
the testing version to check if this happens in those versions too,  
but I'm unable to install any of them - both of them throw such  
exception on 'sudo rake install':

Am I doing something wrong?...
