Instead of a nice colored output I get the following output in the console:

Backtrace: e[0;31m Kernel(Class)#parses_string (method_missing) at kernel/delta/kernel.rb:81e[0m Object#__script__ at test.rb:21e[0m e[0;34m Rubinius::CodeLoader#load_script at kernel/delta/codeloader.rb:68e[0m e[0;34m Rubinius::CodeLoader.load_script at kernel/delta/codeloader.rb:110e[0m e[0;34m Rubinius::Loader#script at kernel/loader.rb:632e[0m e[0;34m Rubinius::Loader#main at kernel/loader.rb:835e[0m

I found some posts describing the same problem but the workarounds didn’t work for me.

Any ideas how to solve this ?
