I do have access to one at work, just not at home (I can only fit so  
many OS partitions on one laptop.)

My feeling about requiring a higher Python version for Tiger remains  

"I'd prefer that we provide an easy means to do the install of Python  
2.6 (ideally a single script you can run, and ideally without

For those of us who still need to support Tiger, it would be a huge  
hassle to have to figure out how to update Python manually to even run
