I mean, that setup.py is intended to be used to build ONLY binary packages.

For me it is strange reaction.... -ba (it means build all, i.e. both 
source and binary rpms). It is usual option. I use rpm-based 
distribution inherited from Mandrake. I should find a RedHat 
distribution to test. OK.

Yes? but it will be not binary package, it requires compilation during 
install.

It just copied in /usr/lib

Probably. I can redo with statical linkong to _gdal...so.
