Hrm... I tried again, with some debugging turned on with dyld, but still 
don't see anything in the output that gives me any clue as to _where_ it's 
looking for the ssl libs nor what exact library name it's hunting for.  I'm 
using Python 2.2 that I believe came with Jaguar...

Do you think it might be a problem with python not knowing where ssl might 
be?  Or the mysql library not being able to find it?
