I installed Snow Leopard yesterday over the August 16 build of MacTeX.  
After doing so, I installed the August 27 build of MacTeX and then  
tried updating font maps. It didn't see updmap, so all I had to do in  
my case was to:

   cd /etc/paths.d

and then:

   chmod 666 TeX

The TeX file already existed. I didn't have to do anything else Dick  
mentions above. Interestingly, a friend  installed in exactly the same  
order and he didn't even have to do what I did -- he just updated font  
maps and was good to go.

On a related note, TeX Live Utility is working nicely and already  
updated 60+ items last night.

I must say that the transition to Snow Leopard and TeX Live 2009 has  
been remarkably painless. No doubt this is do to much hard work be  
many people behind the scenes -- a heartfelt thank you to all of them!

All the best,
