[Gdal-dev] Ogr and Postgis support

[Brian Hamlin]

for what it is worth, I built a PostGIS environment on Mac OSX and it  
works fine. The stock python is I think 2.3. I would have to look up  
the exact order, but I followed some instructions and it all worked -  
install proj, PostgreSQL, GEOS, PostGIS, and build GDAL. Some of the  
environment was picked up by configure, and others I had to help out a  
bit. Looking in the output of configure it was very plain what was  
detected and what was not.

For python, I have since upgraded to 2.5.1, leaving me with two python  
installs, which causes me grief now and then. But basically, the GDAL  
bindings work fine. I installed Numeric and that works fine. I do not  
follwo the talk of NumPy and new Python bindings. I expect that will  
clear up as time goes on, meanwhile I use what I have. A version of  
1.4.2 with my own changes to it.

best regards
   -Brian
