Description of Problem:
Mono fails to build IronRuby and IronPython. It throws an exception.



Steps to reproduce the problem:
1. get source of ironruby git clone git://github.com/ironruby/ironruby.git
2. patch the build script files:
    * replace Merlin/Main/Languages/Ruby/context.rb with the one from the
attachment
3. change line 15 in Merlin/Main/Languages/Ruby/rake/test.rake to read
    require "#{ENV['MERLIN_ROOT']}/Languages/Ruby/Scripts/irtests"
4. export MERLIN_ROOT=/path/to/git/clone/Merlin/Main
5. ensure you have ruby 1.8 and the pathname2 gem installed 
6. rake compile


Actual Results:
