I installed Ruby 1.8.1 on OS X 10.3 using the darwin ports as someone 
suggested.  Now I've also installed rb-cocoa 0.4.0 from the darwin ports.  
Then I tried to run the text reader example from the ruby cocoa page and I 
get:

 phil% /opt/local/bin/ruby speak.rb
dyld: /opt/local/bin/ruby multiple definitions of symbol _rb_obj_clone
/opt/local/lib/libruby.dylib(object.o) definition of _rb_obj_clone
/Library/Frameworks/RubyCocoa.framework/Versions/A/RubyCocoa(single 
module) definition of _rb_obj_clone
Trace/BPT trap


Any ideas?
