3. I installed JRuby through RVM.
4. I ran glimmer setup
5. I ran glimmer scaffold[tahweel_ui]
6. The app works by running glimmer run
7. I ran glimmer package[dmg]
8. The process finished successfully
9. When I mount the dmg file and try to open the app, it just closes
10. I changed directory into the mounted dmg file and ran the app manually using ./Tahweel\ Ui.app/Contents/MacOS/Tahweel\ Ui
11. I got the following error ERROR: org.jruby.embed.EvalFailedException: (NameError) uninitialized constant Glimmer::DSL::SWT::CustomShapeExpression
