  Fixed, thanks.

   Yeah.  Being aware of that sort of danger, I kept telling myself I 
should try these directions out
myself to see whether they could be followed, but I still haven't...

   Of course!  If everybody had the same background knowledge, there 
would be no need for
documentation.  (May have something to do with why some software 
projects don't have
any....)  I've already added a note about that particular effect, as 
mentioned in my last email.

   If you can think of anything else that should be mentioned about 
Mac/Unix differences, by
all means either write something up, or mention the issue and I will.

   Clearly it was a surprise. :)  Also as I said in my last email, I do 
think it's appropriate to
document this, I'm just not quite sure where or what to say.
