I installed IronRuby 0.5, and ran igem install rake, which installed  
Rake 0.8.7.

Now rake/testtask launches new Ruby process using RakeFileUtils.ruby,  
which ultimately calls Kernel.system. When tests fail, $? is examined,  
but it is Fixnum, not Process::Status, so Rake barfs.

Transcript follows.

C:\>iirb  
irb(main):001:0\> require ‘rubygems’  
=\> true  
irb(main):002:0\> require ‘rake’  
=\> true  
irb(main):003:0\> RakeFileUtils.ruby ‘do\_not\_exist.rb’  
C:/ironruby/lib/IronRuby/…/…//bin/ir.exe do\_not\_exist.rb  
NoMethodError: undefined method `exitstatus' for 1:Fixnum from C:/ironruby/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:995:in `sh’  
(snip)

Thanks for the detailed bug report! I have a fix, and will push it out  
next week…
