The problem is not GDAL+UnixODBC - I realize that GDAL was written
with that in mind. The problem is that the only Access ODBC for
_OSX_ that I was able to find that operated directly on files is made
for OSX's built-in iODBC.
Nice to know about mdbtools (I might have seen it before but had no
luck with it, don't remember).
