I have a need to label some images. Seems a good opportunity to learn to use PIL. Using a nice post at
http://www.leancrew.com/all-this/2008/11/truetype-fonts-for-the-python-imaging-library/
led me to Fondu (http://fondu.sourceforge.net/)
which will apparently allow me to use all my truetype mac fonts with PIL. I may post more details if this works.
update: It works!!! Installation involved typical mac package dragging. Nothing else I did was different from the article linked to above.
