 MacRuby 0.4
 There seems to be a problem with method 'open' in open-uri lib.
 Following command:
 {{{
 macruby -r 'open-uri' -e 'open "http://ruby-lang.org"'
 }}}

 produces

Comment:

 We are currently working on the std lib for MacRuby 0.5 and are getting
 pretty close to get open uri working (even though nobody worked on it
 really).

 In the mean time, you might want to use a Cocoa method like NSURLRequest
 etc.. or check my http wrapper: http://github.com/mattetti/macruby-
