*After* I discovered the "opt" symlink, I opened the TeX pref panel.   
When it opened it displayed the 4 distributions I have installed  
(TL2008, TL2009, TL2010, MacPorts).  Then it did a little jig and  
suddenly there was only one (MacPorts).

So: it's possible I did something (e.g., brought the metal plate in my  
head too close to my system) to provoke it, but I don't think the pref  
panel was the culprit.

Am I correct in assuming that the pref panel caches the state of the  
distributions, displays it on the next startup, and after that,  
verifies the setup?

If not, then I'm really confused.
