This looks like a classic and continually frustrating Fusion problem. (Fusion is the .NET loader.) When you use Assembly.LoadFrom, it doesn't automatically add the assembly's directory into any kind of search path. So the dependencies of IronPython.dll can't automatically be found to be loaded. Your best bet for solving this is to put IronPython and all its dependencies into the GAC. It might also work to put the IronPython directory into the path.
