	Very nice suggestion Ryan, thanks! I'd been making assumptions about  
the environment under which a shell script runs, and not only do I  
think I was mistaken in the general case, but also Installer.app seems  
to make the situation even worse by apparently enforcing a very  
specific environment (understandable from the security concerned point  
of view), but then again it could have been just my tired eyes last  
night reading that from /var/log/install.log

	In any case, your suggestion seems straight forward and simple  
enough, so I'll quit trying to reinvent the wheel and will give it a  
shot as soon as I get a few spare minutes (there are some  
implementation details, like nicl for < 10.4 and dscl for Leopard,  
among others).

	Regards,...
