I'm not sure this is connected with teTeX actually. Starting two weeks 
ago some folders on my disk began to inherit fancy ownerships, the 
"user" and "group" associated with them turned into apparently random 
numbers, so that for example I could no longer modify the folder 
/Applications (whereas I am administrator of my computer) apart from 
going back to Terminal.app and using "sudo" for everything; then, for 
example, installer .pkg packages or installer programs reported a "fail" 
to write to this folder.

Then things went even worse : the "user" and "group" were restored to 
real names; unfortunately it wasn't my name but that of another account 
owner on my computer, with no administrator privileges.

Eventually I had to use "chown" for changing every permissions file by 
file and folder by folder, hoping I would guess sensible values and not 
mess anything on my system.

I don't know where this problem comes from. Since I more than often 
experiment with my computer, installing software then removing it, I 
thought I had done something bad at some point. Apparently there are 
several of us experiencing the problem. I thought this could be caused 
by Virex 7.1 (I recently subscribed to .Mac and installed Virex), some 
kind of protection against viruses; and maybe this started when I 
started using Pseudo.app.

There might be something about this problem in Apple's support web 
pages, but I still can't find my way through these pages.
