Hey all, I’m not familiar with ruby or rake, so please forgive the n00b question. Is IronRuby known to currently build on mono 1.9? ./actions/comdispatch/DispCallable.cs(134,9): error CS0452: The type `T' must be a reference type in order to use it as type parameter `T’ in the generic type or method `Microsoft.Scripting.Actions.RuleBuilder'. ./actions/comdispatch/comtypelibdesc.cs(141,9): error CS0452: The type `T’ must be a reference type in order to use it as type parameter `T' in the generic type or method `Microsoft.Scripting.Actions.RuleBuilder'.

[Access Denied](https://bugzilla.novell.com/show_bug.cgi?id=387040) Thanks, John. I’ll ping Marek and see if he can help me fix this. If nothing else, I’ll add the test from that bug to the regression suite. > It’s good to see that Tony’s taken over the mantle of breaking mono 🙂 > > Thanks, > -John Cheers, C.J. ---

Failing test case submitted to mono svn. It should show up in anonsvn in the next 30 or so.
