So how do I turn it off?  I've been using Unix for 40+ years, and I think 
I know what I'm doing: I want to see how "enscript" is calling "lpr" so 
that I can see what is broken ("lpr" works fine by itself).  I suppose 
that I can always futz around with $PATH, but I won't be surprised if it 
doesn't work ("/usr/bin/lpr" could be hard-wired for all I know) and it'll 
have to wait until later.

Let me guess: sign off (losing all my sessions) and sign on again as 
"root" (which I've had to do to restore files outside my home directory 
with Time Machine)?  Install my shim, sign on again as myself, see what's 
wrong, sign on again as "root" to undo what I did to debug a problem, then 
sign on again, repeating as necessary?  Why not just let me modify the 
root file system, and take the responsibility for it?

Sometimes I think that Apple goes too far in protecting users from
