Hi Tomas,

I tried your block of code, but i'm still getting an error.  Are you
getting this error, or do you have rake working?

>>> require 'rake'
E:\IronRuby\trunk\src\IronRuby.Libraries\Builtins\KernelOps.cs:416:in
`require': no such file to load -- rake (LoadError)
        from E:\IronRuby\trunk\src\Microsoft.Scripting.Core\Actions\MatchCaller.Generated.cs:35:in
`Call3'
        from E:\IronRuby\trunk\src\Microsoft.Scripting.Core\Actions\CallSite.cs:275:in
`UpdateAndExecute'
        from E:\IronRuby\trunk\src\Microsoft.Scripting.Core\Actions\UpdateDelegates.Generated.cs:45:in
`Update3'
        from :0

Thanks

Ben
