does anyone knows if there is a bug with zlib and gzip libs?

when I run the sysinfo script in blender I get this


Some expected modules were not found.
Because of that some scripts bundled with Blender may not work.
Please read the FAQ in the Readme.html file shipped with Blender
for information about how to fix the problem.

The missing modules:
-> gzip
-> zlib

I have checked in a python console (python 22) and i can import those libs

in blender console I got this:

Traceback (most recent call last):
File “”, line 1, in ?
ImportError: Module use of python22.dll conflicts with this version of Python.

is it a problem with python or what ?
do I have to install the 23 version of Python ?


Yes, you need Python 2.3.X
