[gdal-dev] Python 3 on Ubuntu 11.10

[David Hodo]

I had installed GDAL from a synaptic package, not source.  I removed the synaptic version and installed 1.9 from source and everything works now.  

Thanks,

David

Did you make a full build of GDAL before trying to build the python bindings ? 
And I also somehow suspect you have GDAL headers from an older version somewhere in your include path, likely in /usr/include or /usr/local/include
