[Gdal-dev] ngpython compile error (python2.5 / amd64)

[Vincent Schut]

I just did a cvs update and saw some files come along that strongly 
suggested the appearance of numpy support in gdal's ngpython module. So 
I thought I'd give it a try. However, on building the ngpython gdal 
extension I get this error, which is possible related to me using 1) 
python2.5, and 2) an amd64 (linux) pc.
