[MacRuby-devel] REXML UTF-8 Encoding not found

Hi Everyone, I am trying to deploy an app that uses XMLSimple and I am getting an error when I try to run the app on computers other than my own. Here is the error message: 11-10-02 9:14:17.289 PM [0x0-0x39039].com.blah.blah: /Users/me/Desktop/MyApp.app/Contents/Resources/rb_main.rb:18:in `block': no such file to load -- rexml/encodings/UTF-8.rb (LoadError) The only difference I can see is my development machine is running ruby 1.9.2 and the test environment is still at 1.8.6. Should the REXML be looking to the MacRuby framework? I am using XMLSimple as a file in my app not a gem.  Any suggestions would be greatly appreciated.  Thank you,  Shaun
