Solved. It looks like it was the Snow Leopard 64 bit defaults that
were breaking things. I must have not updated Xastir since I installed
Snow Leopard! I was able to combine the configure flags that I
originally used to write the HowTo:Mac_OSX with the Snow
Leopard-specific ones added to the wiki by Dick KC8OBZ.

OpenStreetMaps are working great in Xastir!
