You should append to the existing meta_path, not replace it, erasing any  
previous content.
And it must be an *instance* of your importer, not the type itself.
Note that you're polluting the __main__ module namespace by using  
PyRun_SimpleString; I'd use API calls like PySys_GetObject("meta_path")  
and PyList_Append (PEP 302 guarantees it is a list).

Here you append to sys.meta_path, but fail to create the instance first.

You should check the return value; I bet you got a -1 (failure).
