Quick question: How did you manage to deal with proj.4's external data files (e.g. its epsg file and the various datum conversion grids)? In my own GIS-related hacks I had to play some ugly games to get them to install and be located. Actually building the binary "NAD" grids was a fun trick, too. I'm keen to know how you solved that problem.
