It looks like you're using the same Python at the command line as the
Python to which you installed GDAL. There shouldn't be anything else
you have to do once easy-install is complete.
As Miles pointed out, you should probably try this:
from osgeo import gdal
instead of this:
Although I gather the latter should work based on the documentation
I can't see what went wrong with your installation.
You can try an uninstall and reinstall. (`easy_install -m GDAL` might
do the uninstall for you.) If you're feeling adventurous, you can try
to unwind the installation by hand. Edit easy-install.pth and delete
the line that refers to GDAL, and then blow away the GDAL directory in
I see that you originally ran the easy_install from the directory '/
Library/Python/2.5/site-packages'. Don't do that. I don't have a
logical reason for why, but Python given that the current directory is
part of Python's import search path, you might be giving easy_install
a different "environment" than your regular Python session. It's just
a shot in the dark, but worth a try.
Sorry I couldn't be of more help.
