__build_class__ is a (hidden?) function in the builtins module.
Your module isn't completely created yet, it lacks the __builtins__
attribute, so you can't execute any Python code that calls a builtin
function. In 2.5 the class statement was a lot simpler, but in 3.0 it
requires an auxiliary function (implemented as builtins.__build_class__)
You may try setting __builtins__ to the current builtins
(PyEval_GetBuiltins) before executing Python code.
Or, if those 7 lines are all you need, you may just write the equivalent C
code.
