I finally tracked down a bug that was causing an error when trying to  
use rubygems and rake. When a .gemspec was being read and evaluated to  
create a Gem::Specification instance, it was not creating a Gem::Version  
object properly. Turns out that the Version.create() method was checking  
to see if the parameter responds\_to? :version. Somewhere along the line,  
the String class added a version method - which caused the error.

Tomas - The problem seems to be coming from rubygems/custom\_required.rb.  
It redefines Kernel.required() and is not re-throwing the error  
properly:

This works:

module Kernel  
alias gem\_original\_require require # :nodoc:

def require(path) # :nodoc:  
gem\_original\_require path  
end  
end # module Kernel

but this doesn’t:

module Kernel  
alias gem\_original\_require require # :nodoc:

def require(path) # :nodoc:  
gem\_original\_require path  
rescue LoadError =\> load\_error  
raise load\_error  
end  
end # module Kernel

Tomas - Thanks for the advice. However, it is still not working as  
expected. When I run this ruby script:

require ‘rubygems’  
require ‘rake’

puts $LOAD\_PATH

It give me this output:

C:\temp\>ir -D t.rb

`require': Bogus Error (RuntimeError) from C:\Projects\IronRuby\src\Microsoft.Scripting.Core\Actions\MatchCaller.Generated.cs:35:in `Call3’

But the error is actually coming from deep inside the rubygems library

Michael - Thanks for the quick response, but that’s not quite what I  
meant. When I run Ruby and get an error, I get the complete stack trace  
of the Ruby code:

C:\temp\>ruby t.rb  
c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/version.rb:283:in `satisfy?': Bogus Error (RuntimeError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/version.rb:273:in `satisfied\_by?’

`activate' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `require’  
from t.rb:2

However, when I run IronRuby and get an error, I only get one line of  
ruby code and the rest is the C# stack trace:

C:\temp\>ir t.rb  
custom\_require.rb:26:in `require': Bogus Error (RuntimeError) from C:\Projects\IronRuby\src\Microsoft.Scripting.Core\Actions\MatchCaller.Generated.cs:35:in `Call3’

Yes, I found the same thing yesterday :). The patch I submitted for  
review a few hours ago contains a fix for this.
