python in 2.28

hi all

just a question with the new python api how far do the new scripts work?
i noticed that on os x the GUI problem is removed. all guis work now.
also the import math module could be solved by puting the
import sys
sys.path.extend([…])
into the script.

but somehow scripts i rely on like OBJIO_wings_fix.py giving me headages. there is a import blender210 and only import Blender works.
but the script later somehow needs functions or modules wich only Blender210 calls.

any clou or could somebody help me?
