You should look up the discussion that took place in standards@ last year 
or so. There have been some good arguments against using an environment 
variable. It might be better to use the approach other systems like 
Solaris use and put the Posix tools (together with man pages, libraries, 
whatever) into their own directory (/usr/posix, for example). To be 
honest, I have no idea what the best approach is. There are also others
(use a system wide or user configuration file, for example).
