[MacRuby-devel] Using HotCocoa inside a MacRuby project?

Hi all, I'm currently working on a MacRuby project and wanted to use HotCocoa for the window layout features (i.e. circumvent Interface Builder). However, if I include the following lines in rb_main.rb: require 'rubygems' require 'hotcocoa' I get this error: rb_main.rb:9:in `<main>': uninitialized constant MRAReferenceRenderer::KASTargetCurrent (NameError) I'm using MacRuby 0.6 and HotCocoa 0.5.1. Anybody know if it is possible to use HotCocoa within a MacRuby project? Thanks, -Gabriel
