import woes in python

I'm super new on python and i am just deploying an open source app that was done in python and I'm getting a:

ImportError: cannot import name DataSource on from django.contrib.gis.gdal import DataSource

However, this is just fine:

impo开发者_如何学Gort django.contrib.gis.gdal

My current environment setup is:

1. Linux
2. Python 2.7 installed in /opt/python
3. GDAL installed via easy_install like so '/opt/python/bin/easy_install GDAL'
4. Doing #3 looks like it got installed here: '/opt/python/lib/python2.7/site-packages/GDAL-1.7.1-py2.7.egg-info'

Could someone guide me here please?

If i could do import django.contribs.gis.gdal, how come DataSource cannot be imported? I assume DataSource is also part of the GDAL library?

Do you have python-gdal installed? It seems that django.contrib.gis.gdal only exposes the DataSource class if it is installed. At least on Ubuntu, installing python-django didn't install python-gdal by default.

EDIT: as noted in the comments below, you did have it installed, but the module responsible for locating it, django/contrib/gis/gdal/libgdal.py did not find it. If you peek in the source for that module (e.g. http://code.djangoproject.com/browser/django/branches/gis/django/contrib/gis/gdal/libgdal.py?rev=8012), there's a GDAL_LIBRARY_PATH setting that I think you could use to help Django find it.
