Are there any versions of RubyBox that support Ruby 1.8.7?

I am currently using RubyBox 1.4.0 but seem to be running into compatibility issues with Ruby 1.8.7, specifically around an Enumerator call on line 109 of item.rb.

Do any of the earlier versions of RubyBox work as - is with 1.8.7?

If not, any suggestions for a patch so I can successfully backport this gem for 1.8.7?

Thanks,
Wes
