I think you are aware of the error… but I’d like to mention on the list that you can get around it by first installing the gem in MRI that seems to make it go away. » igem install bacon ERROR: While executing gem … (TypeError) allocator undefined for Zlib::Inflate - C:\Users\Ivan Porto C. » gem install bacon Successfully installed bacon-1.1.0 1 gem installed Installing ri documentation for bacon-1.1.0… Installing RDoc documentation for bacon-1.1.0… - C:\Users\Ivan Porto C. » igem install bacon Successfully installed bacon-1.1.0 1 gem installed Installing ri documentation for bacon-1.1.0… Installing RDoc documentation for bacon-1.1.0… ERROR: While executing gem … (TypeError) can’t convert Array into String To install the rails gem there is only one issue remaining and that has to do with a file in the actionmailer test fixtures. The name of the file ends in a ~ and apparently ironruby doesn’t like that. ---

/USUALLY/ filenames ending in ~ are backup files… are you sure the file causes issues is a critical file? ---

The file may be an accidental checkin, but the bug is real. I should be able to handle a file with ~ in the filename.
