[IronPython] MissingMemberException but it definitely exists

[Bob Uva]

I just started using IronPython and am using SharpDevelop as an IDE.
I'm creating a REST web service, and have a class that has a function
named 'run' in it. When I create an instance of the class and then try
calling its run function I get a MissingMemberException saying that
the class has no attribute 'run'. This exception is thrown from
Microsoft.Scripting.Actions.MatchCaller.Call2. Shown below is the call
stack shown in the exception dialog from the IDE. I've even reduced
the run function to just calling pass and that doesn't work. Any ideas
where to look to debug this further?

Thanks,
 Bob
