import visa error (python)

[George2020]

on linux Fedora 19, using python 2.7, I already install NI drivers using the cd rom that came with the gpib board, after issuing the next commands 

import pyPath,time
import re,time,string
import visa

the below error message appears, any suggestions how to fix this? I have already google and try different suggestions but no luck..
