working on a smaller example. i could not get pyNode_root invoked yet
and
PyRun_String("import node\nprint node.root()\n",
Py_file_input,
exec, g_maindict);
triggers Py_CompileString
failure with
Traceback (most recent call last):
File "<string>", line 1, in ?
ImportError: __import__ not found
without RyRun_String call program runs but the pyNode_root is not
invoked
