[MacRuby-devel] Using ORM with MacRuby

I am trying to use Sequel, ActiveRecord or Datamapper with MacRuby and XCode. So far I haven't had any success. Environment: XCode 4.2 Beta MacRuby 0.10 and 0.11-nightly Sequel 3.28 ActiveRecord 3.0.10 Datamapper 1.1.0 Sqlite3 1.3.4 Sqlite-ruby 1.3.3 Both ActiveRecord and Sequel die in IRB (segmentation fault: 11) when I try to access the data table. Datamapper doesn't even load in IRB for me. Has anyone had any success with any ORM in XCode? - Jon
