Thanks for the pointer David, I appreciate it.

I'm using QGIS 1.7.4 on Mac OSX 10.6.8, so I can run ogr2ogr in linux. I'm
not too familiar with running code in terminal, but a friend recomended
installing home brew and xcode first. Do you know of any helpful tutorials
to help a newby get started with running open source command line code?

regards,

-Chris
