Installation permissions

[N Cohen]

I have successfully installed debian v 2.2  on my powerpc  8600  in 
the past and found that XF86Config worked fine when I used it to 
configure the mouse. Now when I install XF86Config comes up with 
permission denied when  I attempt to use it. What has changed I do 
not know. If I use chmod 0755 or g+rx then XF86 will not execute but 
simply shows up as an ordinary file. Please help and many thanks
