Goal: Equip my C# project with a sane, useful IronRuby testing environment that is consistent across OS X and Windows. To that end, I hope to use RVM, Bundler (with binstubs), Rake, RR, and RSpec. Background: Per [Redirecting…](http://www.mono-project.com/Release_Notes_Mono_2.10#Languages:) “Starting with Mono 2.10, we are bundling the open source F# compilers and tools, and the IronRuby [http://ironruby.net/](http://ironruby.net/) and IronPython[http://ironpython.net/](http://ironpython.net/) systems in our Linux packages as well as in our Mac installer.” So, my /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/ contains: bin with all /compiled/ IronRuby assemblies and configs (not including important stuff like gem, etc.), and Lib with a regular ol Ruby standard library with IronRuby goodies mixed in. Problems: - RVM doesn’t support IronRuby at all, and all patches or forks that I found have gone stale. - requirement.rb patch is necessary to even begin using rubygems: [Require 'rubygems' gives llformed requirement ["\>= 0"] (ArgumentError) - IronRuby - Ruby-Forum](http://www.ruby-forum.com/topic/1864531) - Mono’s IronRuby distribution doesn’t include gem/igem, so I ganked it from the Github repo @v1.1.3, but executing something like “ir IronLanguages/Languages/Ruby/Scripts/bin/gem install bundler –backtrace” produces this output: ERROR: Loading command: install (IndexError) Array index is out of range. mscorlib:0:in `GetChars' mscorlib:0:in `GetChars’ mscorlib:0:in `GetChars' mscorlib:0:in `ReadBuffer’ mscorlib:0:in `Read' /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/../Lib/ruby/1.9.1/rubygems/custom_require.rb:28:in `require’ mscorlib:0:in `require' mscorlib:0:in `CallSite.Target’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/../Lib/ruby/1.9.1/rubygems/custom_require.rb:28:in `require’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/../Lib/ruby/1.9.1/rubygems/custom_require.rb:28:in `require’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/../Lib/ruby/1.9.1/rubygems/custom_require.rb:28:in `require’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/../Lib/ruby/1.9.1/rubygems/custom_require.rb:28:in `require’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' mscorlib:0:in `require’ mscorlib:0:in `invoke_object __this___ Func`5\\_CallSite\_RubyScope\_object\_object’ /Library/Frameworks/Mono.framework/Versions/2.10.2/lib/ironruby/bin/…/Lib/ruby/1.9.1/rubygems/custom\_require.rb:28:in `require' ERROR: While executing gem ...

Plea for help: The lack of RVM+Bundler support and all the manual mucking around is definitely sub-optimal; is anyone working on this problem, or does anyone have suggestions on where to start trying to fix it? I really want to show my OS X Ruby brethren all the cool stuff that’s possible with IronRuby, but there’s no way I can make them go through this.
