Hi guys,
I have an addon for old blender-2.49bpy-linux-glibc236-py26-x86_64 and I installed python 2.6.2 but when I run RoRImporter addon I’v got this error

File "/home/slobodan/blender-2.49bpy-linux-glibc236-py26-x86_64/.blender/scripts/RoRImport_0_6_7.py", line 38, in <module>
    import os.path
ImportError: No module named os.path

So I installed python 2.6 from ppa and got blender to find python but when I run addon Im getting

ImportError: cannot import name urandom
