Hi Even, Thanks for the fast responde. That sounds very logic. I built numpy from sources too (numpy 1.5.0) so, what should I do if I want the development packages? I did a python setup.py build --fcompiler=gnu95 python setup.py install Isn't it enough? BTW, I found that http://download.opensuse.org/repositories/home:/ashigabou/SLE_10/x86_64/. I think I'll try it with these packages... >> Hi, >> >> I'm using Python 2.7, with GDAL 1.7.2 bindings.
